Laser in situ keratomileusis for hyperopia

الملخص EN

Purpose : To evaluate the results of Laser in Situ Keratomileusis (LASIK) for hyperopia. Methods : 23 eyes of, 14 patients underwent hyperopic LASIK using , the hansatome corneal shaper and Creator 217-c Chiron (Bausch and Lamb) excimer laser.

patients were divided into two groups based on Preoperative spherical equivalent; group I, spherical equivalent ≤ 5D and group II >5D, The ,following factors were measured post-operatively : Uncorrected Visual Acuity (UCVA), Best spectacle Corrected Visual Acuity (BCVA); refraction (dry, cycloplegic); lines of ,visual acuity ,gained and lost. Results : six months after LASIK, Group I had a mean ±SD spherical Equivalent of +0.22 ± 91D (range -1.19 to +1.63) and, group 2, 2.08:±2.52 (range -0.06 to +8.43).

After six months 66.6% in group I and 45.4% in group II were, within ±ID emmetropia.

UCVA was 20 / 40 or better in 100% in group I and 71.4% in group II.

UCVA remained unchanged or increased in 66.6% in group I and 28.4% in group II.

Thirty three and three tenth percent in group I and 21.4% in group two lost 1 or 2 lines of BCVA. Conclusions : LASIK was predictable and safe for low and moderate hyperopia (MSE ≤ 5D); but for high hyperopia (>5D) is not a good
