Abstract Details

Purpose:

The purpose of this study was to compare clinical and patient recorded outcomes between two patient groups, one after Femto-LASIK and another following SMILE

Setting:

Optegra Eye Hospital Central London in Conjunction with Optegra Eye Sciences

Methods:

Retrospective case series. The study population consisted of 155 non-monovision patients in each prescription-matched group. Patients underwent either SMILE surgery using Zeiss Visumax Laser System (Carl Zeiss Meditec, Germany) or Femto-LASIK within a private eye hospital group in the UK. LASIK ablation was performe dwith the MEL 90 AAA Ablation profile. Unaided distance and near visual acuity (UDVA, DCNVA), spherical equivalent refraction and fluorescein enhanced tear break up time were evaluated pre- and post-operatively. Patient satisfaction data was gathered via an automated questionnaire.

Results:

The unaided binocular distance vision results of non-monovision treatments demonstrated that 99% and 100% of the Femto-LASIK and SMILE groups respectively achieved 6/6 or better by the one month stage. Analysis of monocular distance results showed that 91% (Femto) and 94% (SMILE) achieved 6/6 or better UDVA. Spherical equivalent refraction after surgery was within ±0.50D in 88% (Femto) and 94% (SMILE) treated eyes by one month. Reduction in fluorescein tear break up time was minimal in the SMILE group. Patient reported satisfaction with both procedures was high

Conclusions:

Further research is required to better understand the impact of SMILE on the ocular surface metrics and patient reported outcomes. However, this study demonstrated good results at least equivalent with Femto-LASIK in terms of post-operative refraction and unaided monocular visual acuity with minimal impact on the tear film.
