Clinical evaluation of the safety and efficacy of a new excimer laser system which operates at ?500Hz and uses multidimensional eyetracking.
Maxivision Eye Hospital, Hyderabad, India
: 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.
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
Initial outcomes with the new excimer laser find it provides safe, effective and predictable outcomes. Further data is required to confirm these findings.
