Laser in situ keratomileusis for myopia using manual dissection
1Centro de Recuperacao de Patologias Oculares (CERPO), Brazil.
Summary
Interlamellar photoablation reshapes the stroma for high myopia correction, offering results comparable to LASIK with reduced corticosteroid use. Visual acuity recovery takes 20-90 days post-surgery.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- High myopia presents a significant challenge in refractive error correction.
- Current surgical techniques aim for precise stromal reshaping to improve visual acuity.
Purpose of the Study:
- To evaluate the efficacy and outcomes of interlamellar photoablation for correcting high myopia.
- To compare the results of interlamellar photoablation with established refractive surgery methods like LASIK.
Main Methods:
- Forty-two eyes underwent interlamellar photoablation, involving manual elevation of a stromal disc for excimer laser reshaping.
- A custom nomogram was utilized, with two treatment zones employed for myopia exceeding 10.00 diopters.
- Surgical instruments were standard, and the elevated disc was repositioned to restore the corneal structure.
Main Results:
- The procedure successfully corrected high myopia, with final visual acuity recovery observed between 20 and 90 days.
- Reduced corticosteroid usage was noted compared to other methods.
- One-year follow-up demonstrated outcomes similar to excimer laser in situ keratomileusis (LASIK).
Conclusions:
- Interlamellar photoablation is an effective and simple method for correcting high myopia.
- The technique yields comparable results to LASIK with a potentially favorable side-effect profile regarding corticosteroid use.
- The procedure facilitates corneal healing and visual rehabilitation within a defined postoperative period.
