Purpose
Johnson & Johnson Surgical Vision has developed a new femtosecond laser (aka ELITA). This clinical trial evaluated the ease of lenticule removal and visual outcomes for myopic refractive correction with or without astigmatism, across various optical zones. Results are presented up to 3-months post-operatively.
Setting
A single arm, bilateral, prospective study in myopic subjects ≥18 years from 1 clinical site in Croatia was reported in this study.
Methods
Fifty myopic eyes were treated using the ELITA system, with varying optical zone (OZ) sizes: 7 eyes with 6.0 mm OZ, 12 with 6.5 mm OZ, 9 with 6.7 mm OZ and 22 with 7.0 mm OZ. Main outcomes included an assessment of ease of lenticule removal, uncorrected visual acuity (UCVA), and best corrected visual acuity (BCVA) across different optical zones (6.0, 6.5, 6.7 and 7.0 mm), evaluated up to the 3 month follow-up visit
Results
50 eyes at 1D and 1W post op, 48 at 1M and 42 at 3M across different optical zones were analyzed. Surgeons reported 93% favorable lenticule removal (no/mild dissection) with 13.3%, 20%, 20% and 40% from 6.0, 6.5, 6.7 and 7.0 OZ respectively. Moderate dissection was reported in 2.2% for OZs of 6.0, 6.5 and 7.0 mm, and no cases of difficult dissection were reported. UCVA of 20/20 or better by OZ was: 1W - 74% for 6.0 OZ, 92% for6.5 OZ, 92% for 6.7 OZ, and 73% for7.0 OZ; and at 3M - 93% in 6.0 OZ, 100% in 6.5 OZ, 89% in 6.7 OZ, and 94% in 7.0 OZ. BCVA of 20/20 or better was achieved in 100% of eyes at the 3M f/u.
Conclusions
These results demonstrate that ease of lenticule removal is successfully achieved across multiple optical zones and excellent visual outcomes are achieved with the new ELITA femtosecond laser, concluding that the ELITA femtosecond laser effectively generates lenticules with diverse optical zones.
