Abstract Details

Purpose:

To analyze 5-year- outcomes of a femtosecond-assisted -technique to treat corneal ectasia.

Setting:

'- Clinica Carriazo, Universidad Del Norte, Barranquilla, Colombia - Instituto de la Vision, Universidad de Buenos Aires, Buenos Aires, Argentina

Methods:

110 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 or 360 degree- keratectomy. Once ablation was completed, the edges of the resection were sutured with 8 up to 12 interrupted stitches.

Results:

The age of the population was 33.78 ± 13.05 years-old. Regarding postoperative 5-year-UDVA for 270- degree- arc- length- keratectomy cases (n=49), 59.2% presented 20/100 or worse, and 40.8% achieved between 20/80 and 20/40. After performing PRK in 15 cases, 18.3% of the cases presented 20/100 or worse, 59.1% achieved between 20/80 and 20/40 and 22.6% achieved between 20/30 or better; UDVA for 360-degree-arc-length keratectomy cases (n=61) was analyzed. Also, spherical equivalent, HOAs and gain and lost lines of CDVA were analyzed and moderate to statistically significant differences were found.

Conclusions:

Corneal Remodeling is a safe technique which produces corneal flattening, reduction of anterior chamber depth and decrease of optical aberrations. Also, it offers a possibility to perform refractive complementary procedures on a new corneal profile.
