Purpose
This study aimed to evaluate the effect on tomographic characteristics, quality of life, and surgical history after ten years of corneal collagen CXL in patients with progressive keratoconus (KC).
Setting
Methods
This retrospective cohort study included 68 eyes of patients with progressive KC who underwent CXL at Oftalmosalud Institute of Eyes, Lima, Peru, between June 2006 to June 2011. Visual acuity (VA), subjective refraction, Scheimpflug imaging parameters were evaluated pre and postoperatively at 1 year and at least 10 years of the procedure. Complications, retreatment, combined surgeries, and quality of life was also recorded.
Results
Mean follow-up time was 12.34 years (range 10-14). The best-corrected VA (BCVA) improved 0.03 LogMAR (DS: 0.19, P=0.05). Mean steeper keratometry (K) baseline was 52.68 (DS: 2.88) and 48.20 at 10 years of follow up (p=0.07). 1 patient experienced persistent corneal edema that required corneal transplant. The KC progression rate was 10.29% (7/32), combined procedures were performed in 35% of the cases, the most frequently phakic intraocular lens followed by intrastromal corneal rings trans-photorefractive keratectomy. Retreatment was performed in two eyes with no associated complications.
Conclusions
Corneal collagen CXL is a safe and effective procedure to halt the progression of KC, allowing combined procedures in an effective way and visual recovery higher than expected before.
