Objective
Intrastromal femtosecond laser application is a new treatment option for refractive corrections. The video demonstrates the surgical technique, working principle as well as first results following INTRACOR surgery.
Methods
In a prospective clinical study surgical and functional outcomes of 25 patients following INTRACOR presbyopia treatment (Femtec, Technolas Perfect Vision GmbH) were analyzed. Distance and near visual acuity with different tests as well as corneal topography and further measurements were performed.
Results
All laser surgeries were uneventful and took approximately. 20 seconds. Three months postoperatively mean uncorrected near visual acuity increased from 0.7±0.16 logMAR (0.2 decimal) to 0.26±0.21 logMAR (0.63 decimal). Mean uncorrected distance visual acuity was 0.11±0.11 logMAR (0.8 decimal) preoperatively and 0.05±0.1 logMAR (0.9 decimal) three months postoperatively.
Conclusions
The new femtosecond laser based INTRACOR treatment is a fast, safe and promising method for the treatment of presbyopia. Due to the purely intrastromal laser cuts the risk of infections is much smaller than in many other refractive surgery procedures.
