Summary
Superficial lamellar keratectomy using an automated microkeratome effectively treats anterior corneal opacities, improving vision and comfort. This safe procedure offers advantages over other methods, potentially causing less hyperopic shift than excimer laser treatments.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Anterior Segment Disease
Background:
- Anterior corneal pathologies can impair vision and cause discomfort.
- Superficial lamellar keratectomy is a surgical option for removing corneal opacities.
Observation:
- A retrospective review of 10 eyes (8 patients) undergoing lamellar keratectomy with an automated microkeratome for anterior corneal pathology.
- Mean follow-up was 5.4 months.
Findings:
- All 10 eyes showed improvement in visual acuity and/or ocular irritation.
- Mean improvement in best-corrected visual acuity was 1.8 lines.
- Corneal clarity improved by a mean of 1.8 on a 4-point scale.
- Mean corneal thickness decreased significantly post-procedure.
Implications:
- Lamellar keratectomy with an automated microkeratome is a safe and effective treatment for superficial anterior corneal opacities.
- This technique may induce less hyperopic shift compared to excimer laser phototherapeutic keratectomy.
- It offers specific advantages for selected cases of corneal pathology.
