Frequency of Intraocular Lens Dislocation and Pseudophacodonesis, 20 Years After Cataract Surgery – A Prospective Study

Purpose: To find out the frequency and causes of within the bag intraocular lens dislocation. Study Design: Descriptive, retrospective study. Place and Duration of Study: Federal Government Services Hospital Islamabad, from 2008 to 2018. Methods: Records of all the patients who underwent uneventful phacoemulsification were studied. Patients with Pseudoexfoliation and glaucoma were excluded. Out-of-the bag IOL dislocations and early dislocations that occurred within first three months after the cataract surgery were also not included. Percentage of patients with dislocated lens within the capsular bag after three months or more was calculated and the cause of dislocation was found. Results were presented in percentages. Results: Three thousand patients underwent uneventful phacoemulsification. Two thousand nine hundred thirty two (2932) patients fulfilled the inclusion criteria while 68 patients did not return for follow up. Age ranged between 25 and 75 years. There were 1600 males and 1332 were females. One thousand seven hundred and sixty were right eyes and one thousand one hundred and seventy two were left eyes. Sixty one (2.08%) developed late IOL dislocations, 35 (57.3%) males and 26 (42.7%) females. Patients of age group 50 – 75 years had more IOL dislocations. Causes of dislocation included; advanced mature cataract 21.3%, 19.7% with postoperative trauma, uveitis 14.7%, Myopia 9.8%, Silicon plate design in 9.8%, eccentric capsulorhexis 8.1%, small capsulorhexis 6.5%, retinitis pigmentosa 3.2% and in 6.5% no cause was found. Conclusion: Advanced mature cataract and postoperative trauma were the commonest causes of IOL dislocation. Key Words: Cataract surgery, Phacoemulsification, Trauma, Capsulorhexis.

Purpose: The aim of this article is to describe the safety and efficacy of trans-iris suture fixation for the management of late dislocation of in-the-capsular-bag intraocular lenses following uncomplicated cataract surgery. Patients and methods: Eleven eyes of 11 patients with late in-the-capsular-bag intraocular lens dislocation following uneventful phacoemulsification cataract surgery were recruited in the study. The dislocated intraocular lens–capsular bag complex was sutured to the iris at two points 180° apart using 9-0 polypropylene sutures on long needles. Results: Mean patient age was 67 ± 6 years. Seven eyes had pseudoexfoliation syndrome, one eye had Marfan syndrome, and another eye had a traumatic cataract; no risk factor was identified for intraocular lens dislocation in two eyes. A capsular tension ring had been implanted during cataract surgery in four eyes. In six eyes, the posterior chamber intraocular lenses were one-piece foldable while the remaining were three-piece intraocular lenses. Compared to the preoperative value, corrected distance visual acuity was significantly improved postoperatively ( p < 0.005). Intraoperative hyphema occurred in two eyes. Pupil ovalization was observed in all eyes. Mean endothelial cell count decreased by 4 ± 1.7% after intraocular lens fixation. The capsular bag–intraocular lens complex was stable and well-centered in the pupillary area in all eyes at the final follow-up examination which was performed 16 ± 4 months postoperatively. Conclusion: Trans-iris fixation is a simple and effective procedure for management of late intraocular lenses–capsular bag complex dislocation, without major complications.

A Prospective Study

Background: The aim of the study is to investigate whether the circadian IOP rhythm can be influenced by combined cataract surgery with high frequency deep sclerotomy (HFDS) and whether intraocular pressure (IOP) can be significantly reduced by HFDS. Methods: In our study 10 patients were included, in whom 24 h IOP monitoring was installed before and after HFDS/cataract surgery using a Triggerfish. HFDS is a minimally invasive glaucoma surgery (MIGS). Results: After performed HFDS combined with cataract surgery, the IOP was reduced from 27.7 ± 2.11 mmHg to 14.4 ± 2.59 mmHg, which is highly significant (p < 0.001). The contact lens sensor (CLS) cosinor analysis pre- and postoperatively showed that the circadian rhythm is not influenced by the surgery, i.e., the circadian IOP rhythm did not show significant differences before and after surgery. Conclusions: HFDS combined with cataract surgery is a potent surgical method that can significantly reduce the IOP. However, the circadian rhythm cannot be changed by the surgery. The acrophase remained during the night in all patients.
