To assess the refractive, visual acuity, and binocular results of laser-assisted subepithelial keratectomy (LASEK) in children with bilateral hyperopia or hyperopic anisometropic amblyopia.
Nonhospital surgical facility and hospital clinic, Calgary, Alberta, Canada.
This retrospective review comprised children with bilateral hyperopia or hyperopic anisometropic amblyopia who had LASEK. Refractive status, visual acuity, and binocular vision were assessed and recorded 2 months and 1 year postoperatively.
The mean spherical equivalent (SE) in all 72 hyperopic eyes (47 patients) was +3.42 diopters (D) (range 0.00 to +12.50 D) preoperatively and +0.59 D (range -1.25 to +2.00 D) 1 year postoperatively. After LASIK, 41.7% of eyes had improved corrected distance visual acuity (CDVA). No patient had reduced CDVA or loss of fusional ability; there was a 25.0% improvement in stereopsis at 1 year. The mean anisometropic difference in the hyperopic anisometropic amblyopia subgroup (18 eyes, 10 patients) was 4.39 D (range +1.75 to +7.75 D) preoperatively and +0.51 D (range 0 to +0.875 D) at 1 year. One year postoperatively, 83% of anisometropic eyes were within +/-1.00 D of the fellow eye and 94.0% were within +/-3.00 D. Postoperatively, 64.7% of eyes had improved CDVA with no reduced CDVA or loss of fusional ability; there was a 22% improvement in stereopsis at 1 year.
Laser-assisted subepithelial keratectomy improved visual acuity in pediatric hyperopia with or without associated hyperopic anisometropic amblyopia.
评估双眼远视或远视性屈光参差性弱视儿童行激光辅助上皮下角膜切除术(LASEK)的屈光、视力和双眼视效果。
加拿大阿尔伯塔省卡尔加里的非医院手术机构和医院诊所。
本回顾性研究包括双眼远视或远视性屈光参差性弱视行 LASEK 的儿童。术后 2 个月和 1 年时评估并记录屈光度、视力和双眼视。
47 例(72 只眼)远视儿童的平均等效球镜(SE)术前为+3.42 屈光度(D)(范围 0.00 至+12.50 D),术后 1 年为+0.59 D(范围-1.25 至+2.00 D)。LASIK 后,41.7%的眼矫正远视力(CDVA)提高。无患者 CDVA 下降或融合能力丧失;术后 1 年立体视锐度提高 25.0%。远视性屈光参差性弱视亚组(18 只眼,10 例)的平均屈光参差差值术前为+4.39 D(范围+1.75 至+7.75 D),术后 1 年为+0.51 D(范围 0 至+0.875 D)。术后 1 年,94.0%的眼等效球镜差值在+/-3.00 D 以内,83.0%的眼等效球镜差值在+/-1.00 D 以内。术后,64.7%的眼 CDVA 提高,无 CDVA 下降或融合能力丧失;术后 1 年立体视锐度提高 22.0%。
LASEK 可改善远视儿童的视力,无论是否伴有远视性屈光参差性弱视。
