[Ab] Resumo:PURPOSE: To assess the influence of decentration and aperture size on the optical quality of different intraocular lenses (IOLs) of the same material, body design, and refractive power using standardized optical bench testing. METHODS: Using an optical bench set-up, an aspheric monofocal (CT ASPHINA 409M; Carl Zeiss Meditec, Jena, Germany), an aspheric diffractive bifocal (AT LISA 809M; Carl Zeiss Meditec), and an aspheric diffractive trifocal (AT LISA 839M; Carl Zeiss Meditec) intraocular lens (IOL) were evaluated, each with the same distance power, body design, and material. Modulation transfer function (MTF) values were measured at spatial frequencies of 50 lp/mm and aperture sizes of 3 and 4.5 mm. Each IOL was measured while centered, then decentered by 0.25, 0.5, 0.75, and 1 mm. RESULTS: MTF values for the monofocal IOL at far focus with 3- and 4.5-mm aperture size were 0.80/0.80 with maximum reduction to 0.77/0.73 for 1-mm decentration, respectively. Centered IOL MTFs of the bifocal and trifocal IOLs were lower for the far focus at 0.46/0.41 and 0.39/0.26, with reduction at 1-mm decentration to 0.35/0.25 and 0.25/0.18, respectively. Values for near focus of the bifocal and trifocal IOLs reduced from 0.27/0.31 and 0.19/0.18 to 0.2/0.21 and 0.12/0.13, respectively. The trifocal intermediate focus MTF reduced from 0.15/0.10 to 0.12/0.08. MTF values of all three lenses decreased significantly under all conditions with decentration of 0.5 to 0.75 mm. CONCLUSIONS: Monofocal lenses were least negatively affected by decentration, with mean optical quality reduction of less than 10% for 1-mm decentration at physiological pupil sizes. For diffractive bifocal and trifocal lenses, optical quality at all distances was significantly reduced if decentration exceeded 0.75 mm, with intermediate focus showing the least reduction.

[Ab] Resumo:PURPOSE: To determine whether use of a capsular tension ring (CTR) can increase refractive stability in patients with implantation of two different trifocal intraocular lenses (IOLs). METHODS: A prospective, consecutive series of eyes underwent refractive lens exchange with implantation of two different trifocal IOL designs: FineVision Micro F (non-toric) and FineVision POD FT (toric) (PhysIOL, Liege, Belgium). Power calculation was determined using the Haigis formula. Refractive lens exchange surgery was performed according to the standard Memira protocol. Refractive results and stability were assessed at 2 weeks and 3 months postoperatively. RESULTS: Three hundred eighty-eight eyes were included in the analysis. Overall, 71% and 76% of MicroF eyes implanted with (n = 139) and without (n = 104) a CTR, respectively, had hyperopic shift; 9% of MicroF eyes with a CTR had a shift of greater than +0.50 to +0.75 or less diopters (D) and 4% had a shift of greater than +0.75 D. In MicroF eyes without a CTR, 12% and 3% of eyes experienced a refractive shift of greater than +0.50 to +0.75 D or less and greater than +0.75 D, respectively. In the POD FT group, 72% and 69% of eyes with (n = 81) and without (n = 64) a CTR, respectively, had hyperopic shift; 10% of POD FT eyes with a CTR had a change of greater than +0.50 to +0.75 D or less and 7% had a shift of greater than +0.75 D. In POD FT eyes without a CTR, 13% and 3% experienced a refractive shift of greater than +0.50 to +0.75 D or less and greater than +0.75 D, respectively. For the MicroF design, the best refractive stability was found in the CTR group and the poorest stability in the non-CTR group (P = .084). For the POD FT design, the best refractive stability was found in the non-CTR group and the poorest stability in the CTR group (P = .297). CONCLUSIONS: Up to 7% of eyes implanted with FineVision trifocal IOLs had a hyperopic shift of greater than +0.75 D approximately 2 weeks to 3 months postoperatively. Using a CTR in MicroF eyes had no statistically significant effect on refractive stability. Placing a CTR with POD FT IOLs appeared to reduce refractive stability, although not significantly.

[Ab] Resumo:BACKGROUND: With increasing availability of toric intraocular lenses (IOL) for cataract surgery, real-world refractive outcome data is needed to aid the counselling of patients regarding lens choice. We aim to assess the outcomes of toric intraocular lens use in the non-specialist environment of a typical United Kingdom NHS cataract service. METHODS: A retrospective cohort study conducted at the Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, UK. All patients who received a toric IOL implant over a 10 months period. Patients underwent pre-operative corneal marking, phacoemulsification and toric IOL implantation. Biometry was obtained using a Zeiss IOLMaster 500 and the toric IOLs were selected using the manufacturers' online calculators. Post-operative refractions were obtained from optometrist's manifest refraction or by autorefraction. The outcome measures were post-operative unaided visual acuity (UVA), spherical equivalent refraction, cylindrical correction and all complications. RESULTS: Thirty-two eyes of 24 patients aged 21-86 years (mean 66.4, SD 14.5) were included. UVA was superior to pre-operative best-corrected visual acuity (BCVA) in 81% of eyes, same in 16% and inferior in 3%, resulting in a median improvement of 0.20 LogMAR (IQR 0.10 to 0.30). 56%, 81%, 94% and 100% of eyes were within ±0.5, ±1.0, ±1.5 and ±2.0 D of predicted spherical equivalent, respectively. Three (9%) eyes required further surgery to rectify significant IOL rotation. CONCLUSIONS: Reduced cylindrical correction and improved UVA could be expected in the majority of patients undergoing toric IOL implantation. Patients should be counselled about the risk of lens rotation.

[Ab] Resumo:BACKGROUND: To evaluate the efficiency and practicality of femtosecond laser assisted cataract surgery (FLACS) in a public teaching hospital setting using a mobile FLACS system compared to conventional phacoemulsification cataract surgery (CPCS). METHODS: Ninety eyes from 90 patients underwent either FLACS or CPCS (45 in each group). Cataracts were graded using the Lens Opacities Classification System III system. Outcome measures included total surgery duration, femtosecond laser treatment time, vacuum time (VT), total phacoemulsification time (TPT) and total phacoemulsification power (TPP). RESULTS: No differences were observed in the preoperative mean cataract grades and co-morbidities. FLACS took longer than CPCS with a mean difference of 5.2 ± 4.5 min (range: 0-18.8 min). The average femtosecond laser treatment time was 4.3 ± 3.4 min (range: 1-15.5 min). The VT was 2.51 ± 0.45 min (range: 1.59-4.10 min). Although not significant, TPT in FLACS showed a trend towards improvement (mean 1.0 ± 0.6 s; range: 0.1-2.4 s) compared to CPCS (mean 1.2 ± 0.6 min; range: 0.5-2.5 min). Whereas, TPP was significantly less in FLACS (mean 17.9 ± 5.0%; range: 5-27%) compared to CPCS (mean 20.3 ± 4.1%; range: 12.0-28.7%)(p = 0.031). CONCLUSIONS: The mobile FLACS system housed in the same operating room increased the surgical duration by 5.2 min. The average VT was 2.51 min, which was lower in comparison to published experience using non-mobile FLACS systems.

[Ab] Resumo:PURPOSE: This study compares the presence of vitreous hyper-reflective dots (VHDs) detected with optical coherence tomography (OCT) between eyes with pseudophakic cystoid macular edema (CME) and those with no CME after cataract surgery. In addition, we evaluated the impact of VHDs on the responsiveness of pseudophakic CME to cortisone treatment. SETTING: Department of Ophthalmology, Medical University of Graz, Austria. DESIGN: Retrospective, monocenter case-controlled study. METHODS: Inclusion criteria for the study group and the control group were CME and no CME within 12 weeks following uneventful phacoemulsification in otherwise healthy eyes, respectively. VHDs (number and size) and the macular thickness were assessed with OCT. Furthermore, the number of peribulbar or intravitreal steroid injections was assessed. RESULTS: A total of 284 eyes from 267 patients were analyzed, among which 119 met the inclusion criteria for the study (n = 63) and the control group (n = 56). VHDs were observed in 54 (85.7%) study eyes and 21 (37.5%, p = 0.013) control eyes. The number of VHDs was 3.9±3.4 in the study group and 0.7±1 in the control group (p<0.001). The size of the VHDs was 33.5±9.1 µm and 36.6±17.9 µm in the study and control groups, respectively (p = 0.978). Overall, the number of VHDs correlated with central subfield thickness (r = 0.584, p<0.001), cube volume (r = 0.525, p<0.001), and postoperative best-corrected visual acuity (BCVA) (r = -0.563, p<0.001). The number of VHDs did not correlate with the frequency of peribulbar or intravitreal steroid injections. CONCLUSION: VHDs occurred more often in eyes with CME than in eyes without CME following cataract surgery. In addition, the number of VHDs had an impact on the extent of macular thickening and subsequently postoperative BCVA. No correlation was found between the number of VHDs and the frequency of required peribulbar or intravitreal steroid injections.

[Ab] Resumo:OBJECTIVE: To investigate intraoperative complications, postoperative findings, and visual acuity outcomes in patients with retinal dystrophy after cataract surgery. DESIGN: Retrospective chart review at an academic tertiary referral centre. PARTICIPANTS: Thirty eyes from 18 patients with retinitis pigmentosa and other retinal dystrophies (Usher syndrome, Refsum disease, and Leber congenital amaurosis) who underwent cataract surgery were identified by searching the electronic medical record system from January 2010 to September 2015 for all patients treated by a single physician with billing codes for retinal dystrophy and cataract surgery. METHODS: Cases were reviewed to determine indication for surgery, intraoperative complications, postoperative findings, preoperative visual acuity, 1-month postoperative visual acuity, and patient subjective satisfaction. RESULTS: Mean best-corrected visual acuity significantly improved after cataract surgery, from 1.09 ± 0.69 preoperatively to 0.614 ± 0.448 at 1 month postoperatively, on logMAR scale (p = 0, Wilcoxon test). The most common postoperative finding was posterior capsule opacification in 20 eyes (66.7%). Visually significant cystoid macular edema occurred in 4 eyes (13.3%) despite the postoperative eye drop regimen. Patient satisfaction at 1 month postoperatively was noted as 93.3% (28 eyes) and attributed mostly to improved central vision and reduced glare symptoms. CONCLUSIONS: Patients with visually significant cataract in association with retinal dystrophy have significantly improved best-corrected visual acuity after cataract surgery and report subjectively improved visual functioning. This study confirms that several risks factors are greater in patients with retinal dystrophy, including zonular weakness, posterior capsular opacification, and cystoid macular edema, compared with the general cataract population.

[Ab] Resumo:PURPOSE: To prospectively compare postoperative results of two premium intraocular lenses EnVISTA (Bausch and Lomb) and AcrySof IQ (Alcon), focussing on glistenings and posterior capsule opacification. The evaluation of glistenings was done using Image J software and posterior capsule opacifications were quantified with OSCA system. METHODS: Twenty patients (7 men and 13 women) with bilateral cataract were included. EnVista intraocular lens (IOL) was implanted in one eye and AcrySof IQ IOL in the second eye of each patient. Objective evaluation methods were used for assessment. Glistenings was quantified with ImageJ software and PCO using the Open-Access Systematic Capsule Assessment (OSCA) system (Devised by Aslam TM, Edinburgh, United Kingdom). Complete ophthtalmological evaluation including evaluation after pupil dilatation was done and digital images of intraocular lenses were obtained. The results of 2-, 4-, 6- and 12-month follow-up were compared. RESULTS: Twenty patients were analyzed 2 months, 16 patients 4 months, 14 patients 6 months and 13 patients 12 months after cataract surgery. There was only minimal difference in best corrected visual acuity between EnVista and AcrySof group. The glistenings in the EnVista IOLs was objectively lower than in the AcrySof IOLs during whole follow-up period. In contrast to PCO, in eyes with AcrySof IOL was lower PCO score. CONCLUSION: Development of new materials and techniques of cataract surgery is the topic of ophthtalmologists worldwide. Reduction of glistenings and PCO is one of the main aims, objective measurements is important part of assessment of postoperative results after cataract surgery. KEY WORDS: glistenings, posterior capsule opacification, EnVista, AcrySof IQ, Image J software, OSCA system.

[Ab] Resumo:AIM: The aim of our study was to evaluate the outcome of cataract surgeries with implantation of intraocular trifocal toric lens, and to study the accuracy of astigmatism correction, lens rotational stability, and safety of the procedures. PATIENTS AND METHODS: Our study comprised 22 eyes of 16 patients who underwent unilateral or bilateral implantation of AT LISA tri toric 939MP, or its implantation in combination with AT LISA tri 839MP. Mean patient age was 58 ± 11 years (39 to 75 years). Mean follow-up was 5 months. Evaluated parameters were preoperative and postoperative decimal corrected (CDVA) and uncorrected (UDVA) distance visual acuity. Uncorrected near (UNVA) and intermediate (UIVA) visual acuity was obtained with Jaeger optotypes. Furthermore, we studied manifest refraction, amount of corneal astigmatism, implanted lens position, and potential complications. Using two types of questionnaires we surveyed patients on their subjective satisfaction with vision. RESULTS: Spherical equivalent changed from preoperative -1.32 ± 4.05 D (-9.25 to 4.00 D) to postoperative -0.23 ± 0.21 D (-0.75 to 0.00 D). Preoperative corneal astigmatism was -1.97 ± 0.76 D (-4.02 to -1.01 D), manifest astigmatism was -1.70 ± 1.26 D. After the surgery, manifest astigmatism significantly improved to -0.34 ± 0.37 D (p<0.001). Mean monocular UDVA increased from 0.26 ± 0.18 (0.05 to 0.60) to postoperative 0.88 ± 0.13 (0.60 to 1.00) (p<0.001). CDVA also improved significantly, from 0.57 ± 0.24 to a final value of 1.02 ± 0.07 (p<0.001). Mean postoperative monocular UNVA was Jaeger 1-2, UIVA corresponded to Jaeger 3-4.No serious complications were recorded. Based on the outcome of questionnaires, all patients are satisfied with their vision and they are independent of spectacles. CONCLUSION: In the present study we have obtained very good functional outcomes of vision at far, near and intermediate in cataract patients after trifocal AT LISA tri toric lens implantation. Also, total astigmatism in studied eyes was substantially reduced. The treatment led to a high subjective satisfaction of patients and to their independence of spectacles. KEY WORDS: trifocal toric intraocular lens, cataract, astigmatism, refractive outcomes, patient subjective satisfaction.

[Ab] Resumo:PURPOSE: To analyze internal spherical aberration in pseudophakic eyes that underwent aspheric intraocular lens (IOL) implantation, and to investigate the relationships between biometric data and the effectiveness of aspheric IOL implantation. METHODS: This retrospective study included 40 eyes of 40 patients who underwent implantation of an IOL having a negative spherical aberration of -0.20 µm (CT ASPHINA 509M; Carl Zeiss Meditec Inc., Germany). The IOLMaster (version 5.0; Carl Zeiss AG, Germany) was used for preoperative biometric measurements (axial length, anterior chamber depth, central corneal power) and the measurement of postoperative anterior chamber depth. The spherical aberrations were measured preoperatively and 3 months postoperatively using the iTrace (Tracey Technologies, Houston, TX, USA) at a pupil diameter of 5.0 mm. We investigated the relationships between preoperative biometric data and postoperative internal spherical aberration, and compared biometric measurements between 2 subgroups stratified according to internal spherical aberration (spherical aberration ≤ -0.06 µm vs. spherical aberration > -0.06 µm). RESULTS: The mean postoperative internal spherical aberration was -0.087 ± 0.063 µm. Preoperative axial length and residual total spherical aberration showed statistically significant correlations with internal spherical aberration (p = 0.041, 0.002). Preoperative axial length, postoperative anterior chamber depth, IOL power, and residual spherical aberration showed significant differences between the 2 subgroups stratified according to internal spherical aberration (p = 0.020, 0.029, 0.048, 0.041 respectively). CONCLUSION: The corrective effect of an aspheric IOL is influenced by preoperative axial length and postoperative anterior chamber depth. Not only the amount of negative spherical aberration on the IOL surface but also the preoperative axial length should be considered to optimize spherical aberration after aspheric IOL implantation.

[Ti] Título:Pseudophakic retinal detachment in young-aged patients.

[Ab] Resumo:OBJECTIVE: To investigate the incidence and risk factors for retinal detachment (RD) after cataract surgery or refractive lens exchange (RLE) in patients aged below 61 years. METHODS: Retrospective medical chart review of 7,886 patients (13,925 eyes) who underwent cataract surgery or RLE. Patients aged below 61 years were selected. Age, gender, axial length, follow-up times, and the occurrence of RD were recorded. Additional characteristics documented for RD cases were: history of RD, preexisting retinal findings, laser capsulotomy, status of macula at RD, date and details of RD. RESULTS: From a total of 421 patients (677 eyes) aged below 61 years 24 cases of RD were identified, resulting in an overall cumulative incidence per eyes of 3.55%. The mean follow-up time was 45 ± 32.8 months. Ninety-two % of all RDs occurred within 3.6 years from surgery. Axial length had a significant effect on the risk of RD after cataract/ RLE surgery (HR = 1.42, P = 0.0001, 95% CI 1.19-1.69). The highest incidence of RD occurred in the subgroup of 25 to 28.9 mm axial length (10.2%). With an increase in age of ten years, the hazard of postoperative RD was not significantly increased by a factor of 1.50 (P = 0.286, 95% CI 0.71-3.15). The highest incidence of RD occurred in patients aged 50-54 years (5.39%). Compared to females, males had an almost twofold not significant risk of postoperative RD (HR = 1.96, P = 0.123, 95% CI 0.83-4.63). None of the RD cases had a history of RD. CONCLUSIONS: Axial length is a significant risk factor for pseudophakic RD. The need for cataract surgery or RLE should be carefully considered in patients with axial lengths between 25 and 29 mm, aged 50-54 years, in males, and in case of preexisting retinal findings.
