Lamellar keratoplasty in keratoconus.
Summary
Lamellar keratoplasty significantly improves vision and reduces myopia in keratoconus patients. This corneal surgery flattens curvature and enhances visual acuity, with good graft transparency long-term.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Keratoconus is a progressive eye condition characterized by thinning and bulging of the cornea.
- Visual acuity and refractive errors are significantly impacted in patients with keratoconus.
Purpose of the Study:
- To evaluate the efficacy of lamellar keratoplasty in treating keratoconus.
- To assess changes in visual acuity, corneal curvature, and refractive status post-surgery.
Main Methods:
- The study involved 11 keratoplasty procedures for keratoconus.
- Pre- and post-operative measurements included visual acuity, ophthalmometry, and refractometry (objective and subjective).
Main Results:
- A significant average flattening of corneal curvature (12.84 dpt) was observed.
- Mean myopia reduction was 8.227 dpt, with no alteration to regular astigmatism.
- Mean visual acuity improved from pre-operative levels by 0.495 to a mean of 0.68.
Conclusions:
- Lamellar keratoplasty is an effective surgical option for keratoconus.
- The timing of surgery should be carefully considered based on disease progression.
