Purpose
To analyze 8-year- outcomes of a femtosecond-assisted -technique to treat corneal ectasia.
Setting
Barranquilla, Colombia and Buenos Aires, Argentina.
Methods
Two hundred and twenty-eight cases which underwent Corneal Remodeling were analyzed. Regarding the procedure, anesthetic drops were instilled. A platform designed for femtosecond laser was used to perform the ablation: an 8 mm diameter-270 degree to 360 degree- keratectomy. Once ablation was completed, the edges of the resection were sutured with interrupted stitches.
Results
Age of the population was 30.18 ± 19.57 years-old. At postoperative 9th year, Uncorrected Distance Visual Acuity (UDVA) was 0.43 ± 0.29, spherical equivalent changed from -4.49 ± 3.91 to -0.79 ± 1.95. Also, 100% of the cases changed preoperative Against-the-Rule or Oblique Astigmatism to postoperative With-the-Rule Astigmatism. Corrected Distance Visual Acuity (CDVA) changed from 0.35 ± 0.23 to 0.74 ± 0.32. After performing PRK procedure in 79 cases they achieved UDVA of 20/30 or better. All of the cases gained at least 1 line of CDVA; 52% of the cases gained 4 to 6 lines of CDVA. Postoperative Coma Aberration decreased up to 80%.
Conclusions
Corneal Remodeling is a safe technique. Produces a new corneal flattening, reduction of anterior chamber depth and decrease of optical aberrations. It allows surgeons to perform complementary refractive procedures on new corneal profiles.
