Macular and visual outcomes after cataract extraction for highly myopic foveoschisis

Abstract

To evaluate the macular and visual changes after cataract extraction in patients with myopic foveoschisis. Chang Gung Memorial Hospital, Taoyuan, Taiwan. 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. 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 microm preoperatively, 321+/-108 microm 1 month postoperatively (P<.001), and 347+/-120 microm at 3 months (P=.001). The central foveal thickness stabilized at 6 months (mean 357+/-115 microm). Visual acuity improved and central foveal thickness increased after cataract extraction in patients with myopic foveoschisis. There were no emergent macular changes.
