Abstract Details

Purpose:

To describe a new technique of femtosecond laser assisted intra-corneal ring segment implantation.

Setting:

Oftalmosalud Instituto de Ojos , Lima, Peru

Methods:

The study included 6 eyes of 5 patients. The software of LDV Z6 femtosecond laser was modified to create 110�Â�° reverse side cut between the corneal surface and the incision instead of conventional 90�Â�° angle (which changed the angle between incision and tunnel from conventional 90�Â�° to 70�Â�°) and two disjointed tunnels separated by 10�Â�° arc length at proximal and distal ends.

Results:

At 1-year postoperatively, there were no cases of segment extrusion or touch/overlap. The anterior segment Optical Coherence Tomography showed appropriate position of the rings in all eyes post-operatively. Improvement was also found in visual, refractive, keratometric and asphericity parameters.

Conclusions:

The results of this pilot study are promising. A comparative prospective study with more number of eyes and longer follow-up may confirm if this technique is better than the conventional femtosecond assisted one.
