To report the long term outcomes of photorefractive keratectomy (PRK) for the treatment of hyperopia associated with purely refractive accommodative esotropia.
This study was a retrospective chart review of 40 patients aged 17-39 years who underwent PRK to eliminate their dependence on glasses. Pre- and postoperative best spectacle corrected visual acuity (BSCVA), uncorrected visual acuity (UCVA), refractive spherical equivalent (SEQ), ocular alignment and stereoacuity were reviewed.
Forty patients (80 eyes) with a mean age of 27.9 years were treated for a mean preoperative SEQ of +3.06 D hyperopia. The mean final postoperative SEQ was +0.06 D. Preoperative BSCVA was 0.04 logarithm of the minimum angle of resolution (logMAR), and did not change postoperatively. Mean UCVA significantly improved from 0.30 logMAR preoperatively to 0.08 logMAR post-operatively. Mean pre-operative esotropia at distance and near was 18.6 prism D. All patients were orthophoric without correction at the 1 month, 1 year and final postoperative evaluations. Visual acuity, refractive error and alignment remained stable after the 1 year postoperative examination. Stereoacuity was unchanged in 80% of patients postoperatively. There were no complications.
PRK can be used to treat low to moderate hyperopia associated with purely refractive accommodative esotropia in young adults.
报告准分子激光角膜切削术（PRK）治疗远视合并单纯屈光性调节性内斜视的长期疗效。
本研究回顾性分析了 40 例年龄在 17-39 岁之间的患者，他们接受 PRK 治疗以消除对眼镜的依赖。回顾了术前和术后最佳矫正视力（BCVA）、未矫正视力（UCVA）、屈光球镜等效（SEQ）、眼位和立体视锐度。
40 例（80 只眼）患者的平均年龄为 27.9 岁，平均术前远视 SEQ 为+3.06 D。平均最终术后 SEQ 为+0.06 D。术前 BCVA 为 0.04 最小角分辨对数视力（logMAR），术后无变化。平均 UCVA 从术前的 0.30 logMAR 显著提高到术后的 0.08 logMAR。术前远距和近距内斜视均值为 18.6 棱镜 D。所有患者在术后 1 个月、1 年和最终随访时无需矫正均为正位。视力、屈光度和眼位在术后 1 年检查后保持稳定。80%的患者术后立体视锐度无变化。无并发症。
PRK 可用于治疗年轻成人低度至中度远视合并单纯屈光性调节性内斜视。
