Abstract Details

Purpose:

To evaluate the visual, refractive and optical quality outcomes of laser in situ keratomileusis (LASIK) using a new approach for the calculation of the ablation profile based on wavefront vertexing from pupil plane to corneal.

Setting:

Optilase Eye Clinics, Dublin, Ireland

Methods:

Prospective consecutive case series of 100 eyes of 50 patients (age, 21-41 years) with low and moderate myopia were enrolled. All of them underwent topography-integrated wavefront-guided (TI-WFG) LASIK using the STAR S4IR excimer laser platform (Johnson & Johnson Vision). Visual, refractive, ocular aberrometric, and ocular scattering index (OSI) were evaluated after a 90-day follow-up period.

Results:

A significant reduction in sphere and cylinder (p<0.001) was observed, with a significant improvement in uncorrected (UDVA) and corrected distance visual acuity (CDVA). Postoperative spherical equivalent was within ±0.50 and ±1.00 D in 91.1% and 98.9% of eyes, respectively. UDVA was 20/20 or better in 98.9% of eyes. A total of 50.0% (45/90) of eyes gained 1 line of CDVA. Postoperative high order aberrometric coefficients were below 0.50 μm in 92.2% of eyes. Mean postoperative OSI was 0.71±0.44.

Conclusions:

TI-WFG LASIK is a new approach for myopia and myopic astigmatism correction with preservation of the ocular optical quality
