[Ab] Abstract:Introduction: The phacoemulsification cataract surgery is the most frequently performed surgery and it generally improves vision in over 90% of the patients. Hyperopic patients are a challenge during phacoemulsification especially because of their short eyeball and shallow anterior chamber. A shallow anterior chamber is associated with overall reduction of the safe zone, which may lead to difficulty in creating the corneal incisions, harder capsulorhexis performing, or endothelial complications. Purpose: The aim of the study was to present the endothelial cells loss after the phacoemulsification procedure in the hyperopic patients. Material and Methods: A number of 1775 patients operated in the Ophthalmology Department of the Clinical Hospital Sibiu from January 11, 2011 to December 20, 2013 have been included in our study; 595 cases with emmetropia and the rest of the 1180 patients had the following refraction errors: 216 - myopia and 964 - hypermetropia. From the total cases of the hypermetropia, we selected 72 patients to measure the endothelial cells density and the corneal thickness by using specular microscopy, one day before and 7-14 days after surgery. Results and discussions: The preexisting hypermetropia might modify the intraoperative and postoperative cataract surgery evolution. Endothelial cell loss is potentially higher from surgical trauma so that the endothelium must be protected with viscoelastics. The loss of endothelial cells in hyperopic eyes occurred with an average of 267 cell/ mm² and the thickness of the cornea increased by 13 µm. Conclusion: The phacoemulsification surgery in the presence of hypermetropia requires more attention. The biometry and the specular microscopy are very important tasks for the preoperative assessment, surgery, and postoperative care. The protection of the corneal endothelium with viscoelastics leads to an insignificant modification of the endothelial cells in hyperopic patients compared to an anterior study of the patients with all ametropies.

[Ti] Title:The role of clear lens extraction in angle closure glaucoma.

[Ab] Abstract:Clear lens extraction can be considered a therapeutic option in angle closure glaucoma (ACG). Even if it does not represent the first choice of treatment, it can be taken into consideration when the topical treatment does not control the intraocular pressure (IOP) and iridotomy does not have a positive effect on the angle closure, especially in appositional angle closure when biometry or ultrabiomicroscopy (UBM) show lens involvement. In angle closure glaucoma, clear lens extraction represents an etiological treatment that takes into account the role of the lens in the pathogenesis of the disease. If we ignore it and we choose a filtrating surgery as therapeutic option we can end up with complications such as prolonged athalamia, corneal damage and lens opacification that will eventually require cataract surgery, but performed late and with higher risks. Before performing a filtrating surgery in ACG, we should take an UBM. We also need to choose the best moment to perform surgery, after topical treatment and iridotomy have been tested, but before trabecular damage appears.

[Ab] Abstract:Background: The aim of the study was to evaluate the long-term safety and efficacy of the Trabectome for Chinese glaucoma patients. Methods: This was a multicenter, retrospective, observational study. Glaucoma patients, except those with neovascular glaucoma, with/without a visually significant cataract were enrolled. The patients received Trabectome or a combined surgery with phacoemulsification and intraocular lens implantation. The primary outcome evaluation was a reduction in intraocular pressure (IOP), and the secondary outcomes were a reduction in glaucoma medication, the 2-year success percentages, and complications. Success was defined as an IOP <21 mmHg and at least a 20% IOP reduction from baseline after 3 months for any two consecutive visits, without additional glaucoma surgery. The data were processed using the R Stats Package version 3.0.0. The Wilcoxon test was used to compare the postoperative IOP and the number of glaucoma medications with baselines. The Kaplan-Meier test was used to calculate the 2-year success percentage. The risk factors related to Trabectome failure were determined by logistic regression. Results: A total of 120 glaucoma patients were enrolled. The Trabectome efficiently reduced the IOP from a baseline of 22.8 ± 1.34 mmHg to 17.6 ± 0.96 mmHg, and the use of glaucoma medications from 2.2 ± 0.17 mmHg to 1.4 ± 0.21 in a 2-year follow-up (both, P < 0.01). The overall success percentage was 80%. No risk factor related to Trabectome failure was identified. No vision-threatening complication was observed. Ten patients, who required secondary glaucoma surgery, all reached the target IOP. Conclusions: In a 2-year follow-up, Trabectome was an efficient and safe procedure for Chinese glaucoma patients.

[Ab] Abstract:BACKGROUND: Rupture of the posterior capsule can occur as one of the complications during phacoemulsification. OBJECTIVE: The aim of this study was to determine whether the risk of capsule rupture depends on the surgeon's concentration or experience, time of day and season, the side to be operated on and anatomy of the eye as well as the frequency with which it can be expected. MATERIAL AND METHODS: The patient collective was derived from patients who underwent cataract surgery by phacoemulsification between 2004 and 2014. All surgeries were performed by the same surgeon and constituted no primarily combined operations. Thereby, it was determined how many capsule ruptures occurred, with and without vitrectomy. RESULTS: There were so significant differences between the left or right eye, weekday or month. During the various surgical steps of cataract surgery, the occurrence of capsule rupture was only significantly more frequent at the time of capsule polishing. CONCLUSION: Compared to the results of other studies, the risk of complications was lower in the operation collective investigated in this study.

[Ab] Abstract:Cataract is a total or partial clouding of the lens of the eye. It can be congenital or acquired. Cataract associated with the aging process (senile) is the most common type. Common symptoms include visual impairment which varies based on the type and the density of lens opacity. Cataracts etiology is varied and treatment is based on surgery. In patients with morgagnian cataract cortex liquefies and lens core hardens and becomes cloudy. We here report the case of a 51-year old patient with no notable medical history presenting with progressive decreased visual acuity in the left eye with no pain or redness of the eye associated. Ophthalmologic examination showed visual acuity (the individual can see hand movement), clear cornea, normal anterior chamber depth, an intraocular pressure of 15 mmgh and morgagnian cataract. The patient underwent phacoemulsification cataract surgery with implantation within the capsular bag. Post-operative suites were simple.

[Ab] Abstract:Not every cataract needs phacoemulsification. One problem is the terminological differentiation between "physiological loss of transparency due to ageing" and "cataract". In case of a "real cataract" the autonomous patient must be informed "in any direction". The time of phacoemulsification is determined by the patient and not by the ophthalmologist.

[Ab] Abstract:AIM: to compare the dynamics of epithelial wound healing under two different post-op treatments in patients after uncomplicated phacoemulsification. MATERIAL AND METHODS: This prospective randomized clinical trial included 40 eyes of 40 patients aged 66.4±8.2 years who underwent uncomplicated phacoemulsification with flexible intraocular lens implantation through a 2.2-mm corneal incision. Patients were randomized to receive either dexamethasone 0.1% and diclofenac 0.1% (n=20 eyes, Group I), or bromfenac 0.09% (n=20 eyes, Group II). Also, all patients instilled levofloxacin 0.5%. The dynamics of epithelial wound healing was assessed with the RTVue-100 spectral domain optical coherence tomograph with CAM-L corneal module in the 3D CORNEA mode 2 hours after surgery and on days 1, 3, 5, and 10. RESULTS: The postoperative period was uneventful in all cases. Two hours after surgery, epithelial defects were found in all eyes and their length did not differ statistically p=0.47. On the first day after surgery, complete epithelization was observed in 30% of cases from Group I and 60% of cases from Group II. The average length of epithelial defects was reliably smaller in Group II than in Group I (p=0.04 respectively). On postoperative day 3, 20% eyes from Group I still had epithelial defects with the average length of 0.45±0.13 mm, while there was only one eye with a 0.2-mm epithelial defect in Group II. Finally, on postoperative day 5, there was a single 0.3-mm epithelial defect in one eye from Group I. On day 10, none of the patients had epithelial defects in either group. CONCLUSION: Epithelial wound healing at the site of corneal incision after non-complicated phacoemulsification was found to be faster in patients instilled with bromfenac twice daily than in patients receiving dexamethasone and diclofenac four times daily as anti-inflammatory therapy and given topical fluoroquinolones for antibacterial purpose.

[Ab] Abstract:PURPOSE: To assess the ultrastructural morphologic changes in the surface's micro-roughness for single-use and multiple-use phaco tips after multiple phacoemulsification cycles in an ex vivo animal model. SETTING: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Eight types of phaco tips were studied using an identical experimental protocol. Two tips of each type were used to emulsify porcine cataractous lenses of moderate hardness for 2 minutes. This cycle was then repeated 5 consecutive times for each phaco tip. Scanning electron microscopy and white-light interferometry were used to analyze each tip for potential ultrastructural damage. RESULTS: No significant structural damage was noted on either single- or multiple-use tips after 5 cycles of experimental use. There was a trend toward increased surface micro-roughness at the tip opening after multiple procedures. Most tips had salt crystals on their surface and deposits of organic material composed of carbon and oxygen, which were consistent with porcine tissue that had not been cleaned from the tip surface. CONCLUSIONS: No significant ultrastructural damage was detected after repeated experimental use of phaco tips in a porcine cataract model. There was no significant difference when phaco tips labeled for single use or multiple uses were compared.

[Ab] Abstract:PURPOSE: To examine the outcomes of resident-performed manual small-incision cataract surgery (SICS) in an urban academic setting. SETTING: Parkland Memorial Hospital, Dallas, Texas, USA. DESIGN: Retrospective case series. METHODS: Manual SICS was used only in selected cases for which phacoemulsification was expected to be difficult, namely for mature or brunescent cataracts, traumatic cataracts, and pseudoexfoliation syndrome or other causes of zonular weakness. All manual SICS cases performed by resident physicians as the primary surgeon over a 5-year period were reviewed. Postoperative visual acuity, intraoperative complications, and early postoperative complications were the main outcomes measured. RESULTS: For the 52 cases identified, the mean preoperative visual acuity was 2.165 logarithm of the minimum angle of resolution (logMAR) ± 0.141 (SD) (95% confidence interval) (slightly better than had motion acuity), improving to 0.278 ± 0.131 logMAR (Snellen 20/38) corrected visual acuity postoperatively. Of the 52 cases, the most frequent intraoperative complications were iris prolapse (5 cases [9.6%]) and zonular dialysis (4 cases [7.7%]), with vitreous loss occurring in 1 case (1.9%). The most frequent postoperative complications were cystoid macular edema (3 cases [5.8%]), retained ophthalmic viscosurgical device (2 cases [3.8%]), intraocular lens displacement (2 cases [3.8%]), and microhyphema (2 cases [3.8%]). CONCLUSIONS: Although the more advanced wound construction in manual SICS might be challenging to surgeons unfamiliar with the technique, it was a safe and efficacious technique in the hands of learning residents. With several advantages over phacoemulsification, such as cost and ability to remove very dense nuclei, manual SICS will play a valuable role in modern cataract surgery.

[Ab] Abstract:PURPOSE: To determine the clinical characteristics and outcomes of patients with toxic retinopathy after phacoemulsification and intraocular lens implantation when the correct cefuroxime dilution is administered. SETTING: State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China. DESIGN: Prospective case series. METHODS: Patients developing toxic retinopathy after phacoemulsification between January 2016 and April 2017 were observed. All patients received an anterior chamber injection of correctly diluted cefuroxime at the end of the surgery. RESULTS: The study evaluated 20 patients (20 eyes). At the 1-day follow-up, the mean logarithm of the minimum angle of resolution (logMAR) corrected distance visual acuity (CDVA) decreased to 0.78 logMAR ± 0.31 (SD) with no significant difference compared with the preoperative CDVA of 0.71 ± 0.34 logMAR (P = .535). Spectral-domain optical coherence tomography (SD-OCT) showed cystoid macular edema (CME) with extensive serous neurosensory retinal detachment (RD) at the posterior pole. At the 1-week follow-up, the mean CDVA improved to 0.13 ± 0.80 logMAR and the improvement was significant compared with the preoperative and 1-day postoperative logMAR CDVA (P < .001). The SD-OCT showed regression of CME and recovery of RD. CONCLUSIONS: When the drug dilution is correct, there is still a possibility of sporadic cefuroxime toxic maculopathy after intracameral injection of cefuroxime. This toxicity might be related to transient retinal pigment epithelium sodium-potassium pump dysfunction resulting from a large injection volume of a standard dose concentration or individual differences in conventional drug dose tolerance.
