Abstract

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. Intra ocular lens dislocation.
