Abstract

Aim: To analyze the clinical and functional outcomes of correction of high myopia in eyes with the first stage of keratoconus using femtosecond laser-assisted intrastromal MyoRing implantation. Materials and methods: Thirty eyes (15 patients) with the first stage of keratoconus and high myopia underwent femtosecond laser-assisted intrastromal MyoRing implantation. Mean corneal thickness was 468 ± 12.4 μm. MyoRings were inserted in the intrastromal pockets with diameter 9.0 mm at the depth of 300 μm using femtosecond laser IntraLase FS 60 kHz. Results: Mean uncorrected visual acuity (UCVA) value increased from 1.2 ± 0.03 to 0.3 ± 0.1 logMAR 6 months after operation, mean best corrected visual acuity (BCVA) value increased from 0.24 ± 0.09 to 0.18 ± 0.03 logMAR. Then UCVA and BCVA values remained practically unaltered during the whole follow-up period. Conclusion: The MyoRing implantation stabilizes the keratoconus by enhancing the biomechanical properties of the cornea and simultaneously improves visual acuity due to correction of high myopia.
