Abstract Details

Purpose:

To evaluate efficacy of Laser in situ Keratomileusis (LASIK) procedure for the correction of high hypermetropia with astigmatism.

Setting:

Eye Clinic Svjetlost Sarajevo

Methods:

Retrospective study of 130 patients (216 eyes)  with hypermetropia between +4.00 and +7.00 diopters (D) and cylinder up to 2.00 D who underwent LASIK procedure.All ablations were performed with Wavelight Allegretto Eye-Q 400 Hz excimer laser  (Alcon, Forth Worth, TX, USA). All flaps were made with Moria M2 (Moria, Antony, France) mechanical microkeratome (90µm head). Preoperative and postoperative uncorrected and corrected distant visual acuity (UDVA, CDVA), spherical equivalent (SE) and aberrometry for 5mm pupil were measured. Measurements were taken at 1 week, 1, 3 and 6months after the surgery. Wilcoxon Signed Ranks Test was used for statistical analysis.

Results:

Postoperative UDVA was lower than preoperative CDVA at 1 week (p=0.001), same at 1 month (p=0.099), and  at 3 and 6months UDVA was better (p<0.0001).Preoperative SE was 4.69 ± 1.20 D (+4.75 to +7.50 D). At 1 week SE was 0.03 ± 0.67 D (-0.50 to +0.63 D), while at 1 year regressed to 0.58 ± 0.56 D (+0.25 to +0.88 D).There was significant difference in SE at every time point (p<0.0005).There was a significant increase in coma (p<0.0001), trefoil (p<0.0001, p=0.0006) and spherical aberration (p=0.022, p=0.0052) in1 month postoperatively, without change throughout the rest of follow up.

Conclusions:

LASIK for high hypermetropia with astigmatism showed prosperous results in postoperative refraction with insignificant regression and without decreased visual acuity. On the other hand to asses optical quality more test are needed.
