To investigate the efficacy and safety of LASIK for the correction of anisometropia in adult patients.
A retrospective, case series. From a random sample of 1190 patients from the cornea and refractive service we found 14 adult patients that underwent monocular LASIK/PRK for anisometropia. We evaluated the preoperative and postoperative refractive error, spherical equivalent (SE), uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Snellen visual acuity measurements were converted to LogMAR for statistical purposes.
The mean age was 33.2(±12.2) years. The average preoperative SE in the treated eyes was -1.96(±3.69), the average SE of the untreated eye was 0.25(±0.30). Preoperative UCVA was 0.99(±0.34) and average preoperative BCVA was 0.26(±0.15). 13 patients had LASIK and only one patient had PRK with an average follow-up time of 15.8(rank 1-74) months. The average postoperative SE decreased to -0.24(±0.33)(p=0.11). Four patients (28.6%) gained 1 line of vision, 1 (7.14%) patient gained 2 lines of vision, 1 patient lost 1 line of vision (PRK patient), the rest remained unchanged compared to preoperative BCVA. There was a significant difference between UCVA pre [0.99(±0.34)] and postoperative [0.24(±0.13)](p <0.001). There was no significant difference between postoperative UCVA with preoperative BCVA (p = 0.16). There were no complications related to surgical procedures.
Monocular refractive surgery in adult patients with anisometropia is a safe and effective therapeutic option that offers a satisfactory visual outcome, preserving or improving the preoperative BCVA.
