Summary
Cataract surgery with intraocular lens implantation is safe for patients with diabetic retinopathy and iris neovascularization. Careful management of diabetes is crucial to prevent complications.
Area of Science:
- Ophthalmology
- Diabetic Retinopathy Management
- Surgical Outcomes
Background:
- Iris neovascularization historically contraindicates intraocular surgery.
- Proliferative diabetic retinopathy (PDR) poses risks for ocular procedures.
Purpose of the Study:
- To evaluate the safety and efficacy of cataract extraction with posterior chamber lens implantation in patients with rubeosis iridis due to PDR.
- To determine if this procedure is associated with unacceptable intraoperative or early postoperative complications.
Main Methods:
- Retrospective analysis of 39 eyes from 33 patients with manifest iris neovascularization and PDR undergoing cataract extraction.
- Data reviewed for preoperative, intraoperative, and early postoperative complications and visual outcomes.
Main Results:
- Posterior chamber intraocular lenses were implanted in 35 eyes.
- Intraoperative iris hemorrhage occurred in 10 eyes, more frequently with nuclear expression than phacoemulsification (P=.019).
- Postoperative complications included resolving hyphema (7 eyes) and reversible fibrin (6 eyes); no severe sight-threatening complications were noted. Visual acuity improved in 85% of eyes.
Conclusions:
- Cataract extraction and posterior chamber lens implantation are associated with acceptable complication rates in patients with iris neovascularization.
- Optimal management of diabetic retinopathy before and after surgery is essential to prevent neovascularization progression.
