Abstract Details

Purpose:

To evaluate the possible risk factors and the clinical results of femtosecond laser implanted intrastromal corneal ring segments extrusion in keratoconic eyes

Setting:

Sohag Refractive Center, Sohag, Egypt

Methods:

A retrospective interventional consecutive study evaluated Keraring ICRS that were explanted in Sohag Refractive Center, Sohag, Egypt from January 2013 to January 2018, The study included eyes with Keraring extrusion of keratoconus patients with tunnels created by femtosecond laser. The causes, risk factors and clinical outcomes (including visual and corneal topographic outcomes) were evaluated for all eyes

Results:

Different causes were responsible for keraring extrusion including chronic allergy with eye rubbing, chronic sun exposure with ocular dryness and atopic dermatitis. Female sex, age less than 22 years old, thick ring segments, large arc segments and advanced Keratoconus were the most important risk factors. The ring extrusion resulted in visual and corneal topographic deterioration in the keratoconic eyes

Conclusions:

Various factors participate in Keraring extrusion after femtosecond laser implantation. Marked worsening of visual and corneal topographic parameters ocurred after keraring explantation
