An image analysis study of cataract development after trabeculectomy with mitomycin C.

We prospectively measured quantitative changes in the crystalline lens after trabeculectomy with mitomycin C. Twenty-four eyes in 24 trabeculectomy cases were consecutively enrolled in the study. The enrollment criteria consisted of: phakic eye, no history of intraocular surgeries and no corneal opacification. The transparency of the lens was measured and analyzed by EAS-1000 preoperatively, then 1 and 3 months postoperatively. Changes occurred primarily in the anterior part of the lens, especially in the anterior subcapsular region. The multivariate regression analysis demonstrated an association of cataract development with age, myopic refraction, difference in preoperative and postoperative IOP and systemic hypertension.
