Abstract
Purpose: To determine incidence of progression of cataract and interval to cataract surgery in phakic patients receiving intravitreal triamcinolone acetonide (4 mg) injection.
Methods: IVTA was given in 100 phakic eyes of 98 patients for various pathologies causing macular edema. Patients with follow up for 1 year retrospectively included. Lens status, best-corrected visual acuity, intraocular pressure recorded at each follow up. We also noted duration to cataract surgery. Cataract progression analyzed by lens scores using LOCS III.
Results: The mean follow-up time was 15 months. At the last follow-up, out of 21 clear lens cases lens opacity increased in 19 cases of which 7 posterior sub-capsular cataracts, 5 nuclear sclerosis grade I, 5 had lens changes, 2 operated at 6 months. Out of 39 lens changes, 33 had progression in lens opacity of which include 21 PSC, 11 NS I, 3 NS II, 1 case remained the same and 1 developed mature cataract. 83% received single injection of which 46.98% underwent surgery at a mean of 14 months. 15% received 2 injections, of them 46.66% operated at 16 months. 2 received 3 injections both underwent surgery at mean of 24 months. 48% underwent surgery at duration of 15 months.
Conclusions: Cataract formation became visually significant in t half of eyes and required surgery by one year after injection. Most of these cases known to have worsening of macular edema with cataract surgery, alternative treatment modalities may be a better option for reducing macular edema in phakic eyes.
