Purpose:
|
To evaluate the efficacy of Wavefront-guided photorefractive keratectomy(PRK) for correction of residual refractive error after Intrastromal corneal ring segments(ICRS) insertion for treatment of keratoconus.
|
Methods:
|
In this prospective case series five eyes of 5 keratoconus patients who had previously Intacs implantation(four IntacsTM and one Keraring) ,underwent Wavefront-guided PRK for residual refractive error correction.
|
Results:
|
Three months postoperatively, mean spherical equivalent (SE) improved from -2.07 Diopter±1.38 (SD) (range -3.75 to -0.25 D) to -0.87±0.54 D (-1.50 to 0.00). Four eyes of 5 were within ±1.00 D of Plano refraction. Three eye had UCVA of 20/30 or better (all eyes;20/40 or better). After 6 months, mean SE was -0.75±0.50 D (range -1.12 to 0.13 D). All eyes were within ±1.00 D of Plano refraction. UCVA was 20/20 in 2 eyes, 20/30 or better in 2 eyes and 20/40 in one eye. one patients lost one line of BCVA.
|
Conclusion:
|
This case series showed that Wavefront-guided PRK is an effective and safe procedure for correction of residual refractive error after ICRS insertion in keratoconus patients.Significant improvementin UCVAwas seen in all cases after PRK without any complications and haze.We recommend topical MMC application during PRK.
