Myopic excimer laser keratectomy: a preliminary report.

Area of Science:

• Ophthalmology
• Laser Surgery

Background:

• Myopia correction is a significant area of ophthalmic research.
• Excimer laser photorefractive keratectomy (PRK) offers a surgical option for refractive errors.

Purpose of the Study:

• To evaluate the safety and efficacy of excimer laser refractive keratectomy for myopia correction.
• To assess visual acuity, refractive stability, and corneal healing post-PRK.

Main Methods:

• Six patients with myopia underwent excimer laser PRK.
• Corneal epithelium was removed, and laser ablation was performed to achieve emmetropia.
• Ophthalmologic evaluations and visual acuity measurements were conducted postoperatively.

Main Results:

• Five out of six patients achieved 20/20 best corrected visual acuity by the 12th postoperative week.
• The procedure resulted in good wound healing and minimal corneal scarring in most cases.
• One patient developed a central corneal opacity due to non-compliance with steroid therapy, impacting visual acuity.

Conclusions:

• Myopic excimer laser PRK is associated with good wound healing and stable refractive outcomes.
• The procedure can lead to excellent visual acuity with proper patient compliance.
• Excimer laser PRK is a viable option for myopia correction with a favorable safety profile.
