Abstract Details

Purpose:

The purpose of this study is to evaluate the long-term accuracy, efficacy, safety and stability of laser in situ keratomileusis for the treatment of hyperopia.

Setting:

Smahliou Eye-Clinic, Athens, Greece

Methods:

This retrospective, consecutive study comprised of 292 eyes of 151 patients (98 females and 53 males) who underwent LASIK to correct hyperopia. Mean age of the participants was 55.05 ± 9.73 years (range 26-72 years). The mean preoperative sphere value was 2.74 ± 1.45 (range 0 – 7.50) diopters (D) and the mean cylinder value was -0.83 ± 1.03 (range -6.00-0) D. The preoperative and postoperative measurements included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), subjective manifest refraction and slit lamp biomicroscopy. Mean follow up was 13.41± 2.14 years (range 8-15 years).

Results:

UDVA improved from 0.93 ± 0.62 logMAR to 0.12 ± 0.64 logMAR. The mean preoperative attempted spherical equivalent (SE) was 2.66 ± 1.48 D. At the last follow up visit the mean achieved correction was 0.56 ± 0.48 D. In addition, 22.26% of the eyes were in the ±0.50 range and 72.94% were in the ±1.00 range of the attempted correction. Refractive stability was noted in the 1st postoperative month, while hyperopic regression was noted after the 4th postoperative year. 20 patients (39 eyes-13.36%) had a second LASIK operation (Redo). Mean Redo time was 6.51± 2.04 years (range 4-10 years).

Conclusions:

Laser in Situ Keratomileusis is effective and safe for correcting both UDVA and BCVA postoperatively. However, a mild regression of the refractive effect was observed over the last follow up visit and a small percentage of patients underwent a second LASIK operation as an enhancement due to hyperopia regression at least 4 years after the first LASIK procedure. Therefore, the long-term stability of hyperopic LASIK is doubtful and questionable.
