Evaluation of the Efficacy of Intracameral Tropicamide 0.02% Injection for Mydriasis in Manual Small-Incision Cataract Surgery(Code-T0277)

Introduction: Mydriasis is crucial for effective visualization and surgical precision during cataract surgery. Manual Small-Incision Cataract Surgery (MSICS) relies on adequate pupil dilation to facilitate optimal surgical outcomes. Tropicamide is a commonly used agent for mydriasis, but the efficacy of intracameral tropicamide 0.02% injection in MSICS is not well documented. This study evaluates the efficacy of intracameral tropicamide for inducing mydriasis in MSICS.

Aims and Objective:

Aim:

To Evaluate efficacy of Intracameral Tropicamide injection 0.02% for mydriasis in Manual small-incision cataract surgery (MSICS) .

Objective:

1.To check sustainability of dilatation of Pupil at various stages of cataract surgery with the use of 0.02% Intracameral Tropicamide Injection.

1. To compare sustainability of Pupil Dilatation with 0.02% Intracameral Tropicamide Injection with respect to Age and Gender at various stages of surgery.

3.To compare Pupil Dilatation between Topical Tropicamide eye drops used in Pre-examination period Versus dilatation with Intracameral Tropicamide Injection.

Methods: A prospective, non-randomized study was conducted on 100 patients undergoing MSICS. Patients were administered intracameral tropicamide 0.02% following corneal incision. Pupil diameter was measured before and after injection, with assessments at 10-minute intervals until the surgery was completed. The onset and duration of mydriasis, as well as any complications, were recorded.

Results: Intracameral tropicamide 0.02% achieved sufficient mydriasis in 98% of cases, with a rapid onset within 5–10 minutes and sustained dilation throughout surgery. The procedure was well tolerated, with no significant complications or adverse effects reported. In comparison to topical agents, intracameral tropicamide provided more consistent and longer-lasting mydriasis.

Conclusion: Intracameral tropicamide 0.02% is an effective and safe alternative for inducing mydriasis in MSICS, offering rapid and sustained pupil dilation with minimal complications.
