Visual outcome of implantable phakic contact lens

Abstract

Aim To evaluate the visual outcome of implantable phakic contact lens (IPCL) in high myopia. Setting Al-Mashreq Eye Center, Cairo, Egypt. Patients and methods Thirty eyes of 17 patients underwent surgery to correct high myopia using IPCL (Care Group-India) with a central hole (V2.0). Visual acuity, spherical equivalent, and intraocular pressure (IOP) were evaluated 6 months postoperatively. Anterior chamber parameters Anterior chamber volume (ACV), Anterior chamber depth (ACD), Anterior chamber angle width (ACAW) were measured using Pentacam. Results After 6 months, spherical equivalent decreased from −14.19±4.2 to −0.18±0.66 D, all cases were within ±1.00 D of intended correction. Best corrected visual acuity (BCVA) remained unchanged in 13% of cases, 13% gained one line, and 74% gained two or more lines. ACV, ACD, and ACAW decreased from 189.77±20.19 mm3, 3.15±0.27 mm, and 37.31±5.63° to 131.4±14.01 mm3, 3.05±0.29 mm, and 23.94±4.81°, respectively. Changes in IOP between preoperative and 6 months postoperatively were statistically insignificant. Conclusion IPCL is a safe, effective, and predictable surgery to correct high myopia. Most cases gained one or more lines of BCVA. Reduction of ACV did not induce IOP rise during 6 months of follow-up.
