Abstract

Purpose: To present the efficacy of combined PTK, PRK and CXL in management of progressive keratoconus over one year follow up.

Setting: An-Najah National University Hospital, An-Najah National University, Nablus, Palestine.

Design: Retrospective descriptive study.

Methods: A total of 43 eyes of 36 patients with progressive keratoconus underwent combined PTK, PRK and CXL. Visual, refractive, pachymetric and keratometric preoperative and postoperative follow-up data (at 1 month, 3 months, 6 months, and one year) were taken from the patients’ medical records.

Results: the mean UDVA improved from (0.33 ± 0.19) preoperatively to (0.64 ± 0.27) at one year postoperatively and the mean CDVA, from (0.62 ± 0.21) to (0.80 ± 0.20), respectively. The mean spherical and cylindrical values changed significantly from (-2.10 ± 2.45) postoperatively to (-0.34 ± 2.26) postoperatively and from (-3.50 ± 1.85) to (-1.23 ± 1.02), respectively. The mean steep and flat K readings decreased significantly from (50.97 ± 4.46) to (47.58 ± 5.61) and from (47.08 ± 4.02) to (44.84 ± 4.47), respectively. The mean K max also decreased from (56.27 ± 6.40) preoperatively to (51.22 ± 7.94) postoperatively. The mean thinnest corneal thickness was (462.49 ± 36.17 μm) preoperatively and (388.21 ± 56.64 μm) postoperatively.

 

Conclusion: the combined PTK, PRK and CXL has shown to be efficacious in management of progressive keratoconus. Impressive improvements in visual, refractive, pachymetric and keratometric values were noted.
