Abstract Details



Purpose:

Clinical evaluation of the safety and efficacy of a new excimer laser system which operates at ?500Hz and uses multidimensional eyetracking.

Setting:

Maxivision Eye Hospital, Hyderabad, India

Methods:

: A single surgeon, single centre clinical study where 34 patients underwent a bilateral aspheric treatment algorithm for distance vision using an excimer laser (Bausch + Lomb Technolas). Target refraction was plano. Measured outcomes included uncorrected and best corrected visual acuity, refraction, stability, safety and ease of use. Patient follow-up was 1 day, 1 week, 1 month and 3 months.

Results:

Mean pre-op spherical equivalent (SE), sphere and cylinder were -3.86D ḟ2.17D, -3.57ḟ2.11D and -0.58ḟ0.61D. Mean patient age was 26.4 years. At 1 week follow-up, SE, sphere and cylinder were 0.01ḟ0.21D, 0.01ḟ0.20D and -0.01ḟ0.06D. At 3 months post-op (18 eyes), all patients had monocular uncorrected distance visual acuity (UDVA) of 1.0 or better, with 94.4% at 1.2 or better. All patients had binocular UDVA of 1.2 or better. 44.4% of patients gained 1 line of best correct distance visual acuity (BCDVA), with 5.6% losing 1 line of BCDVA. The safety index was 1.1

Conclusions:

Initial outcomes with the new excimer laser find it provides safe, effective and predictable outcomes. Further data is required to confirm these findings.
