[Ab] Resumo:To present a novel and simplified surgical technique of Artisan lens implantation for intraocular lens luxation and aphakia in glaucoma patients with previous superior filtration surgery. Analysis of 12 patients with a history of previous superior filtration surgery for glaucoma, who underwent artisan lens implantation. To allow lens manipulation and implantation without alteration of the filtration bleb, the main sclerocorneal incision was performed laterally and the Artisan lens was held in place for enclavation of the iris stroma via a superior corneal incision without disturbing the filtration bleb. Mean pre-operative visual acuity was 0.54 ± 0.85 LogMAR, and intraocular pressure (IOP) was 15.8 ± 7.7 mmHg. At the end of follow-up (11.6 ± 8.1 months), visual acuity had improved to 0.32 ± 0.57 LogMAR and intraocular pressure was 14.7 ± 5.4 mmHg. No disturbance of the filtration bleb was observed. Artisan lens implantation can be performed successfully via a combined lateral and superior approach despite the presence of a filtration bleb at the 12 o'clock position.

[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.

[Ti] Título:Changing patterns in treatment of angle closure glaucoma.

[Ab] Resumo:PURPOSE OF REVIEW: Angle closure glaucoma is a leading cause of blindness globally and trends of how best to treat this disease are evolving. The advent of anterior segment imaging aids our understanding of pathogenesis and allows more robust and objective measurement of treatment modalities. We will also review recent literature regarding the role of laser and surgical interventions for the treatment of primary angle closure disease. RECENT FINDINGS: Recent studies evaluating the efficacy of laser peripheral iridotomy (LPI) in primary angle closure suspects (PACs) show that while it is a safe intervention and initially anterior chamber angle widens following the laser treatment, the effect is lost with time. Only a small minority of PACs patients develop primary angle closure (PAC) or primary angle closure glaucoma (PACG). Trials evaluating argon laser peripheral iridoplasty (ALPI) have failed to show a substantial clinical benefit. In patients with early or moderate PACG and those with PAC with IOP over 30 mmHg, clear lens extraction is associated with better clinical and quality of life outcomes than LPI. SUMMARY: Recent evidence supports initial clear lens extraction in the context of PACG or primary angle closure with IOP more than 30 mmHg.

[Ab] Resumo:PURPOSE: Our purpose was to assess the early intraocular pressure (IOP) changes of ultralow fluence laser iridotomy using pattern scanning laser followed by neodymium:yttrium-aluminum-gamet (Nd:YAG) laser. METHODS: This is a prospective interventional study. Thirty-three eyes of 33 adult Chinese primary angle-closure suspect subjects were recruited for prophylactic laser peripheral iridotomy. Sequential laser peripheral iridotomy was performed using pattern scanning laser followed by Nd:YAG laser. Visual acuity (VA) and IOP were measured before treatment, at 1 h, 1 day, 1 week, 1 month, 3 months and 6 months after laser. Laser energy used and complications were documented. Corneal endothelial cell count was examined at baseline and 6 months. Patency of the iridotomy was assessed at each follow-up visit. RESULTS: All subjects achieved patent iridotomy in a single session. The mean energy used was 0.335+/-0.088 J for the pattern scanning laser, and 4.767+/-5.780 mJ for the Nd:YAG laser. The total mean energy was 0.339+/-0.089 J. None of the eyes developed a clinically significant IOP spike (≥ 8 mmHg) at 1 h and 1 day after laser use. Only four eyes developed higher IOP at 1 h and all were ≤3 mmHg compared to baseline. The mean IOP was 13.8+/-2.5 mmHg at 1 h and 11.5+/-2.2 mmHg at 1 day, both were significantly lower than baseline (15.8+/-2.1 mmHg) (P < 0.001). Mean VA (logMAR) was similar at 1 h post laser compared to baseline (0.23 vs 0.26). There was also no statistically significant difference in mean VA at other follow-up visits compared to baseline. Peripheral iridotomy closure was encountered in two (6.1%) eyes, one at 1 month and another at 6 months follow-up. There were no complications including hyphema, peripheral anterior synechia formation nor prolonged inflammation throughout the follow-up period. There was no significant loss in corneal endothelial cell counts at 6 months (2255+/-490) compared to baseline (2303+/-386) (P = 0.347). CONCLUSIONS: Sequential LPI using an ultralow fluence pattern scanning laser, followed by a Nd:YAG laser, is safe and efficacious, and produces no IOP spike in dark irides of primary angle-closure suspects. Further studies to investigate its role in the treatment of other angle-closure conditions are warranted.

[Ab] Resumo:Introduction: Urrets-Zavalia syndrome is an uncommon complication of the deep anterior lamellar keratoplasty in keratoconus. The manifestations of this syndrome are an irreversible mydriasis, iris atrophy and secondary glaucoma. Case report: Deep anterior lamellar keratoplasty was done for keratoconus with a presumably healed corneal hydrops in a 21-year-old Caucasian man. The graft remained clear, but the surgery was complicated by a fixed, dilated pupil, patches of iris atrophy, ectropium of the iris pigment layer and glaukomflecken in the lens. Conclusion: Although safer than penetrating keratoplasty, the deep anterior lamellar by not trying to secure an unhealed Descemet's membrane with air. Instead, a new Descemet's membrane transplanted within a penetrating graft is a safer choice.

[Ti] Título:Wavefront control in adaptive microscopy using Shack-Hartmann sensors with arbitrarily shaped pupils.

[La] Idioma:eng
[Ab] Resumo:In adaptive optical microscopy of thick biological tissue, strong scattering and aberrations can change the effective pupil shape by rendering some Shack-Hartmann spots unusable. The change of pupil shape leads to a change of wavefront reconstruction or control matrix that should be updated accordingly. Modified slope and modal wavefront control methods based on measurements of a Shack-Hartmann wavefront sensor are proposed to accommodate an arbitrarily shaped pupil. Furthermore, we present partial wavefront control methods that remove specific aberration modes like tip, tilt and defocus from the control loop. The proposed control methods were investigated and compared by simulation using experimentally obtained aberration data. The performance was then tested experimentally through closed-loop aberration corrections using an obscured pupil.

[Ti] Título:Extending the depth of field with chromatic aberration for dual-wavelength iris imaging.
[So] Source:Opt Express;25(25):31696-31707, 2017 Dec 11.
[Is] ISSN:1094-4087
[Cp] País de publicação:United States
[La] Idioma:eng
[Ab] Resumo:We propose a method of extending the depth of field to twice that achievable by conventional lenses for the purpose of a low cost iris recognition front-facing camera in mobile phones. By introducing intrinsic primary chromatic aberration in the lens, the depth of field is doubled by means of dual wavelength illumination. The lens parameters (radius of curvature, optical power) can be found analytically by using paraxial raytracing. The effective range of distances covered increases with dispersion of the glass chosen and with larger distance for the near object point.

[Ab] Resumo:A 23-year-old female patient presented 3 months after the implantation of an Artisan® phakic intraocular lens with a severe depigmentation of the iris and peripheral anterior synechiae. Explantation of the intraocular lens and goniosynechialysis were performed. Eleven months after the explantation appearance of the iris significantly improved. There was no loss of lines of corrected distance visual acuity. Severe pigment dispersion after the implantation of an Artisan® phakic intraocular lens may happen and may require explantation of the lens. Iris depigmentation may improve with time.
