Discrepancy between Actual and Theoretical Anterior Chamber Depth in Patients with Morcher Posterior Chamber Intraocular Lens

Purpose: Cataract surgery is the most common ocular surgery worldwide and in modern era of phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation, refractive aspects of surgery is as important as the surgery itself. After the IOL implantation, the anterior chamber depth (ACD) is increased and the iridocorneal angle is widened. These changes should be considered for accurate IOL selection. In this study we evaluated the actual ACD following implantation of Morcher foldable PC IOL and compared it with the predicted depth. Methods: In a cross-sectional analytic study, ninety four cataractous eyes were operated with standard phacoemulsification and a foldable PC IOL (Morcher Bio Com Fold Type 93 IOL) was implanted. ACD, axial length (AL), refraction, and visual acuity were checked before and 3 months after the surgery. Results: ACD after the surgery was significantly increased, but it was smaller than the predicted depth (5.61 mm). Best corrected visual acuity (BCVA) after the surgery was significantly improved. There was a myopic trend in postoperative refraction. Conclusion: ACD after cataract surgery combined with Morcher Bio Com Fold type 93 lens was different from the predicted depth and this made most patients myopic.
