Preoperative parameters, such as subjective refraction, anterior chamber depth (measured using a pentacam), and white-to-white diameter were measured. A custom-made IPCL using the aforementioned parameters was then implanted in the sulcus to correct moderate to high myopia. All patients had undergone neodymium-doped yttrium aluminum garnet peripheral iridotomy.Results: Clinical outcome data were collated retrospectively from the medical case records of the patients. The mean age was 25.36 years (standard deviation [SD]: 3.60 years), and 55.55% of the patients were men. The mean preoperative best-corrected visual acuity (BCVA) was 0.367 logmar units (SD: 0.266, max: 0.0 and min: 1.2). The post-IPCL implantation mean uncorrected visual acuity was 0.225 logmar units (SD: 0.172, max: 0 and min: 0.7), which was significantly superior to the preoperative BCVA (P=<0.0001). Forty-three patients (86%; satisfaction scores of ≥4; scale 1–5) were “highly satisfied” to “extremely satisfied” with the outcome. The mean follow-up period was 1.8 years.Conclusion: Implantation of the IPCL with peripheral holes in the intraocular posterior chamber resulted in a clinically significant improvement in unaided visual acuity. Long-term follow-up showed optimum stability of vision.Keywords: IPCL, pathological myopia, peripheral optical hole
