To compare and evaluate improvement in corrected distant visual acuity (CDVA) between myopia and hyperopia after Laser in situ Keratomileusis (LASIK) in adult patients with anisometropic amblyopia.
Eye Clinic Dr Ismail
This prospective clinical study included 103 amblyopic eyes from 103 patients which underwent LASIK correction of refractive error at a single centre from January 2017 to October 2019. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity, spherical equivalent (SE), postoperative astigmatism and intraocular pressure (IOP), were evaluated at time point of one, six and 12 months.
Patients were divided in two groups according to refractive error ﾖ group one patients with myopia and group two patients with hyperopia. Postoperative CDVA in group one was 0.17ﾱ0.13 and 0.32ﾱ0.17 in group two. Group one showed more expectable results, 95% of variability achieved SE was dependent on SE intended (R2=0.95), while in group two the percentage was slightly lower of expected 87% (R2=0.87). There was statically significance in respect of CDVA change postoperatively and preoperatively in both groups. Correlation factors are low, in group one r=-0.53 and in group two r=-0.39.
LASIK can improve CDVA in a considerable portion of amblyopic eyes, both myopic and hyperopic. Eyes with better initial CDVA, and those with myopia were associated with greater improvement in postoperative CDVA.
