Short term results with excimer laser-photo-refractive keratectomy

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Photo-refractive keratectomy (PRK) is a common refractive surgery procedure.
• Excimer lasers are widely used for corneal reshaping.
• Assessing the predictability and outcomes of PRK is crucial for patient satisfaction.

Purpose of the Study:

• To evaluate the outcomes of PRK using the Meditec Mel 60 laser.
• To assess the predictability of refractive correction at three months post-surgery.
• To analyze results for both myopic and hyperopic patients.

Main Methods:

• A retrospective analysis of 86 eyes (68 myopic, 18 hyperopic) that underwent PRK.
• Data collected at three months post-operative.
• Analysis of refractive outcomes and predictability within +/- 1D and +/- 2D.

Main Results:

• For myopia less than 6D, 86% achieved +/- 1D predictability; for myopia over 6D, 68% achieved +/- 1D.
• Predictability within +/- 2D was 96% for myopia less than 6D and 85% for myopia over 6D.
• In hyperopic patients, the mean refractive change was 2.7D, with 44% within +/- 1D at three months.

Conclusions:

• The Meditec Mel 60 laser demonstrates good predictability for PRK in myopic and hyperopic corrections.
• Outcomes are generally favorable, with higher predictability in lower myopia.
• PRK with this laser system offers a viable option for refractive error correction.
