Background and objectives: To evaluate anterior capsule opening (ACO) contraction and late intraocular lens (IOL) dislocation after cataract surgery in patients with weak or partially absent zonular support and assess methods of reducing these complications. Materials and methods: For this prospective study, we enlisted cataract surgery patients in our hospital with preoperative diagnoses of weak zonules. All patients received phacoemulsification surgery with implantation of a hydrophobic acrylic IOL and capsular tension ring (CTR). ACO reductions were measured for six months after enrolment. Data on late IOL dislocations were collected five years after enrolment of the last patient. Results: Fifty-three patients were enrolled from 2011 to 2015. Over the six-month active follow-up period, ACO area reduction was 23% in patients receiving CTRs of 11 mm diameter and 8% for patients with CTRs of 12 mm, with an overall mean of 15% reduction. Five years after the last patient was enrolled, seven patients (13%) had experienced late IOL-CTR-capsular bag dislocation. For these patients, the mean ACO reduction in the first six months of follow-up was 33%, including for those who had received neodymium-doped yttrium aluminum garnet (Nd: YAG) anterior capsulotomies. Conclusion: Use of hydrophobic acrylic lenses and CTR reduces ACO contraction, with rates comparable to those after cataract surgery without ocular comorbidity. Our patients experienced a relatively high rate of late IOL-CTR-capsular bag dislocation. However, dislocated complexes were easily repositioned and few patients required IOL exchange. Frequent visits are warranted to promptly detect late complications of cataract surgery in patients with weak zonular support.

Retinal Straylight

Purpose. To investigate the intraocular straylight value after cataract surgery.Methods. In this study, 76 eyes from 62 patients were subdivided into three groups. A hydrophobic acrylic, a hydrophilic acrylic, and a PMMA IOL were respectively, implanted in 24 eyes, 28 eyes, and 24 eyes. Straylight was measured using C-Quant at 1 week and 1 month postoperatively in natural and dilated pupils.Results. The hydrophilic acrylic IOLs showed significantly lower straylight values than those of the hydrophobic acrylic IOLs in dilated pupils at 1 week and 1 month after surgery (P<0.05). However, the straylight values of the hydrophilic acrylic IOLs were the lowest among the three IOL groups. No significant difference was observed in straylight between 1 week and 1 month postoperatively in each group with natural and dilated pupils (P>0.05). Moreover, no significant difference was found in straylight between natural and dilated pupils in each group at 1 week and 1 month postoperatively (P>0.05).Conclusions. Although the hydrophobic acrylic IOL induced more intraocular straylight, straylight differences among the 3 IOLs were minimal. Pupil size showed no effect on intraocular straylight; the intraocular straylight was stable 1 week after surgery.

Background: Advancements in cataract surgery have necessitated the availability of intraocular lens preloaded delivery systems that can safely, effectively and predictably deliver IOLs in the eye. Preloaded delivery systems simplify and reduce procedural variability during surgery preparation. Objective: The objective of this study was to evaluate clinical acceptability, delivery characteristics and clinical outcomes in patients implanted with new generation hydrophobic acrylic Intraocular Lens with Preloaded delivery system. Methods: This was a single centre retrospective study. Total 41 patients were enrolled in the study to get at least 38 patients for evaluation. All patients were assessed on day1 and 1, 3 and 6 months after surgery. Results: EYECRYL-SERT showed ‘excellent’ ease of insertion and handling in all 41(100%) patients. Corrected Distance Visual Acuity (CDVA) improved from 0.74±0.58 logMAR during screening to 0.03±0.04 logMAR 6 months after surgery. The Corrected Intermediate Visual Acuity (CIVA) and Corrected Near Visual Acuity (CNVA) were 0.10±0.04 and 0.01±0.02 logMAR post 6 months surgery, respectively. The refractive spherical equivalence was -1.94±2.51 D during screening, which improved significantly (p=0.0018) to -0.21±0.47 D post 6 months surgery. The low and high contrast sensitivity was 0.06±0.06 and -0.05±0.06 logMAR after 6 months surgery, respectively. The endothelial cell loss was 5.67%, 7.22% and 9.75% at 1, 3, and 6 months after surgery, respectively, as compared to screening. None of the subjects reported any adverse event during the study period. Conclusion: The IOL delivery system (EYECRYL_SERT) provided desired delivery characteristics during cataract surgery and was effective in improving clinical outcomes in cataract patients.
