Macular and visual outcomes after cataract extraction for highly myopic foveoschisis

Purpose: To evaluate the macular and visual changes after cataract extraction in patients with myopic foveoschisis. Setting: Chang Gung Memorial Hospital, Taoyuan, Taiwan. Methods: This retrospective study reviewed the charts of 20 eyes (14 patients) with myopic foveoschisis that had phacoemulsification. All eyes except 1 had intraocular lens implantation. The preoperative and postoperative best corrected visual acuities (BCVAs) were documented. The central foveal thickness and morphology were examined by optical coherence tomography. Results: The mean postoperative follow-up was 15.6 months ± 9.6 (SD). The mean preoperative BCVA of 1.35 ± 0.65 logMAR improved to 0.47 ± 0.38 logMAR 1 month after surgery (P<.001) and to 0.40 ± 0.40 logMAR at 3 months (P<.001 versus preoperatively; P = .01 versus 1 month). The BCVA stabilized to a mean of 0.40 ± 0.41 logMAR at 6 months and was 0.37 ± 0.39 logMAR at the last visit. The mean central foveal thickness was 297 ± 107 μm preoperatively, 321 ± 108 μm 1 month postoperatively (P<.001), and 347 ± 120 μm at 3 months (P = .001). The central foveal thickness stabilized at 6 months (mean 357 ± 115 μm). Conclusions: Visual acuity improved and central foveal thickness increased after cataract extraction in patients with myopic foveoschisis. There were no emergent macular changes.
