Abstract Details

Purpose:

To compare refractive outcomes, visual acuities, and satisfaction of patients between those treated with LASIK using a Hansatome microkeratome (HM) and femto-assisted laser (FAL).

Setting:

Hashmanis Hospital, Karachi, Pakistan

Methods:

This was a retrospective analysis of 1,366 eyes in 687 patients undergoing LASIK with HM (n=1,137) and FAL (n=229) at the two centers of Hashmanis Hospital, Karachi, Pakistan. Refractive outcomes, including Sphere (D), Cylinder (D) and Spherical Equivalent (D) and visual acuities were assessed both preoperatively and at 1 month follow-up. Patient satisfaction was gauged by contacting the patient at the time of chart review.

Results:

The postoperative median sphere, cylinder and spherical equivalent values for those treated with FAL were 0.3 ± 0.7 (-5.5 - 1.8), -0.5 ± 0.6 (-5.0 - 1.0), and 0.0 ± 0.7 (-6.0 - 1.6), respectively. For the HM arm, they were 0.0 ± 1.28 (-10.8 - 6.8), -0.5 ± 0.5 (-4.5 - 1.5), and, -0.3 ± 1.3 (-11.6 - 6.8), respectively. All preoperative values were statistically insignificant between the groups while postoperative values were significant with p-values < 0.001. Predictability and efficacy index was higher for FAL (92.1%, 1.00) than the HM group (82.2%, 0.84). Similarly, patient satisfaction was slightly higher for those treated with FAL (93.3%) than HM (91.4%).

Conclusions:

Our large retrospective analysis of eyes undergoing LASIK using HM and FAL show superior refractive outcomes in the latter, with special regards to procedural efficacy and predictability.
