Abstract Details

Purpose:

To evaluate the safety and effectiveness of the ALLEGRETTO WAVE® Eye-Q Excimer Laser for Topography Guided LASIK treatment of manifest and cornea-based myopic refractive errors.

Setting:

Prospective, non-randomized, multicenter, clinical study, at 9 US

Methods:

Eligible subjects 18 years of age or older with myopia up to -9 D sphere and 6 D cylinder underwent Topography Guided LASIK as primary treatment. The treatment plan was created using the ALLEGRO Topolyzer image files and the Topography Guided Custom Ablation Treatment Software. The ablation was performed with the ALLEGRETTO WAVE® Eye-Q laser system. Subjects completed 12 months of follow-up. Assessments included uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) measured with an ETDRS chart at 4 meters, manifest refraction at 4 meters, aberrometry with the Wavelight Analyzer and patient reported outcomes with the RSVP questionnaire.

Results:

Two hundred and forty seven eyes underwent treatment. Refractive stability was demonstrated at 3 months. At 3 months, 92.7% of eyes had UCVA of 20/20 or better, 91.9% of eyes had MRSE within ± 0.50 D of target and 0% of eyes lost two or more lines of BCVA. At 3 months, nearly 40% of eyes had either a reduction or no change in spherical aberrations compared to baseline. The RSVP showed an improvement in all subscales at 3 months or later postoperatively compared to baseline. Dry eye was the most frequent complication at 3 months or later.

Conclusions:

The ALLEGRETTO WAVE® Eye-Q Excimer Laser System used for Topoguided LASIK is effective and safe in treating myopia as primary treatment.
