To report the surgical and refractive outcomes of femtosecond laser (FS) incisions for cataract and refractive lens exchange surgery. To analyze safety profile and endotelial cell loss.
Oftalvist Alicante. Alicante, Spain
Prospective, consecutive, single-surgeon study. A total number of 245 eyes were included in the study. One hundred fifteen eyes underwent FS laser cataract and refractive lens exchange surgery with FS incisions (Catalys, Optimedica). Fifty two eyes underwent FS laser with manual incisions. Controls underwent standard phacoemulsification cataract extraction. FS laser plus incisions group treatment included an attempted 5.0 mm capsulorrexis, a standarized lens fragmentation pattern limited to 7 mm, and a 2.1 mm main incision placed in the deepest axis for astigmatisms over 0.75 D. Manual incisions were performed with a 1.9 metal blade following the same protocol. Side port incision was placed at 45ŗ in both cases, FS and manual. Main outcome measures included refraction, keratometry, intraoperative complication rates and endotelial cell counts.
Groups were comparable for patient demographics. One hundred percent of capsulotomies were complete with no tags or tears. One month postoperative spherical equivalent was comparable between groups, 84-85% of patients ± 0.5 D and 94-100% ± 1.0D. Surgical induced astigmatism (SIA) varied between groups: 0.21±0.15 D in FS laser incisions group vs. 0.30±0.25 D in the manual incisions group, FS and standard phacoemulsification. There was a reduction in the mean endotelial cell count in the FS group at one month (-144.85±152.9 vs. -170.35±229.62).
Femtosecond laser incisions for cataract and lens exchange refractive surgery do not increase surgical induced astigmatism (SIA) compared to manual incisions, being a safe and reproducible new technology.
