Summary
Persistent corneal edema after cataract surgery (ICCE) occurred in 2.3% of patients. The type of intraocular lens significantly impacted this risk, with specific anterior chamber lenses showing higher rates.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Cataract Surgery
Background:
- Persistent corneal edema is a potential complication following cataract surgery.
- Intracapsular cataract extraction (ICCE) is a surgical technique for cataract removal.
- The choice of intraocular lens (IOL) may influence postoperative outcomes.
Purpose of the Study:
- To determine the incidence of persistent corneal edema after ICCE.
- To investigate the impact of different intraocular lens types on the development of persistent corneal edema.
Main Methods:
- Retrospective analysis of 1041 ICCE procedures with at least eight years of follow-up.
- Calculation of cumulative incidence of persistent corneal edema.
- Comparison of edema incidence across subgroups based on IOL type.
Main Results:
- Overall cumulative incidence of persistent corneal edema was 2.3%.
- Incidence varied by IOL type: 1.0% for Choyce anterior chamber lens, 10.3% for 3-M style 77 anterior chamber lens, and 1.4% for no IOL.
- Patients with persistent corneal edema had higher re-operation rates (27.3%) compared to those without (4.4%).
Conclusions:
- Persistent corneal edema occurs in 2.3% of patients after ICCE.
- Significant differences in persistent corneal edema frequency exist based on IOL type.
- The Choyce anterior chamber lens was associated with the lowest incidence, while the 3-M style 77 anterior chamber lens had the highest.
