Abstract Details

Purpose:

To evaluate the visual, refractive and aberrometric outcomes 2 years after LASIK surgery for the correction of myopia using aspheric ablation profiles and the solid-state laser technology

Setting:

Department of Ophthalmology (Oftalmar), Medimar International Hospital, Alicante, Spain

Methods:

A total of 166 eyes with myopia or myopic astigmatism of 88 patients with ages ranging from 20 to 52 years (mean age: 33.6±7.6 years) were included. In all cases, LASIK surgery was performed for the correction of the refractive error using the microkeratome M2 (Moria) and the solid-state laser Pulzar Z1 (CustomVis). Aspheric ablation profiles were programmed in all cases. Visual, refractive and aberrometric (iTrace system) were evaluated 1 and 2 years after surgery.

Results:

Mean spherical equivalent (SE) was reduced significantly from a mean preoperative value of -3.58±1.74 D to a mean postoperative value of +0.01±0.24 D (p<0.01) and +0.01±0.19 D (p<0.01) at 1 and 2 years after surgery, respectively. A total of 92.2% and 98.4% had an SE within ±0.50 D of emmetropia at 1 and 2 years after surgery, respectively. Uncorrected distance visual acuity improved significantly from a mean preoperative value of 1.05±0.39 LogMAR (range, 0.00 to 1.70) to a mean postoperative value of 0.02±0.06 LogMAR (p=0.01) and -0.05±0.06 LogMAR (p=0.01) at 1 and 2 years after surgery, respectively. A total of 17.7% and 38.1% of eyes gained one or more lines of corrected distance visual acuity at 1 and 2 years after surgery, respectively. Mean efficacy and safety indices at 2 years postoperatively were 1.04±0.23 and 1.08±0.22. Mean preoperative Zernike term for primary spherical aberration (5-mm pupil) was +0.03±0.09 µm and changed postoperatively to a mean value of +0.15±0.12 µm and +0.12±0.08 µm at 1 and 2 years, respectively. This change reached statistical significance (p<0.01), but was small in magnitude, with postoperative levels of spherical aberration within the physiological range of the human eye.

Conclusions:

LASIK surgery for the correction of myopia using aspheric ablation profiles and the solid-state laser technology is safe and efficacious at short and medium term, with a minimal induction of spherical aberration.
