Summary
Keratomileusis in situ offers a new surgical option for high-grade myopia, with good visual recovery and minimal scarring. This intrastromal keratectomy technique preserves Bowman
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Context:
- Photorefractive keratectomy (PRK) using excimer lasers is a common refractive surgery.
- Intrastromal keratectomy methods offer alternatives for myopic patients.
- High-grade myopia presents unique surgical challenges.
Purpose:
- To present the initial outcomes of keratomileusis in situ for treating high-grade myopia.
- To evaluate the safety and efficacy of this intrastromal corneal surgical technique.
Summary:
- Keratomileusis in situ was performed on 15 amblyopic eyes with high myopia (-12 to -25 D).
- The procedure involves resecting a refractive lenticule from the corneal stroma and resuturing a lamella.
- Postoperative refraction averaged -1.37 D, with visual acuity recovery within 4 weeks and minimal scarring in most cases.
Impact:
- Keratomileusis in situ demonstrates potential as a supplementary technique for high-grade myopia correction.
- The procedure offers rapid visual rehabilitation and maintains corneal transparency.
- Preservation of Bowman's layer integrity contributes to an almost scar-free optical zone.
