Visual and Refractive Outcomes with a New Topography-integrated Wavefront-guided Lasik Procedure

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Laser in situ keratomileusis (LASIK) is a common refractive surgery procedure.
• Advancements in ablation profile calculation aim to improve visual outcomes and patient satisfaction.

Purpose of the Study:

• To evaluate the clinical outcomes of a new LASIK ablation profile calculation method.
• To assess the efficacy of topography-integrated wavefront-guided (TI-WFG) LASIK for myopia and myopic astigmatism correction.

Main Methods:

• A prospective case series of 100 eyes from 50 patients with low to moderate myopia.
• TI-WFG LASIK performed using the STAR S4IR excimer laser platform.
• Evaluation of visual, refractive, aberrometric, and patient satisfaction outcomes at 90-day follow-up.

Main Results:

• Significant reduction in sphere and cylinder, with improved uncorrected and corrected distance visual acuity (UDVA and CDVA).
• 91.1% of eyes achieved a postoperative spherical equivalent within ±0.50 D; 98.9% achieved within ±1.00 D.
• High-order aberrations and ocular scattering index (OSI) remained low, with high patient satisfaction reported.

Conclusions:

• TI-WFG LASIK with the new ablation profile is effective for myopia and myopic astigmatism.
• The procedure preserves ocular optical quality.
• High patient satisfaction is associated with TI-WFG LASIK outcomes.
