All-in-One Femtosecond Laser Refractive Surgery
Shah, Rupal MS*; Shah, Samir MTech, MS*; Vogelsang, Hartmut†
Purpose: To describe techniques (FLEx and SMILE) for performing all-in-one Femtosecond Laser Refractive Surgery, without using an excimer laser.
Methods: The VisuMax femtosecond laser is used to carve out a refractive lenticule from within the corneal stroma, and then the lenticule is physically removed, either by creating and lifting a flap of the cornea, or by extracting it from a small incision.
Results: The technique gives results which are stable, effective, safe and predictable.
Conclusions: All-In-One Femtosecond Laser Refractive Surgery is a new technique of performing corneal laser refractive surgery. It has clinical, practical and economic benefits over a traditional two-laser solution.

Results of Small Incision Lenticule Extraction: All-in-one Femtosecond Laser Refractive Surgery
Authors: Rupal Shah, Samir Shah, Sayantan Sengupta
To report the clinical results of small incision lenticule extraction to correct refractive errors using a femtosecond laser to refine the femtosecond lenticule extraction technique.
Private laser center, Vadodara, India.
Prospective clinical study.
The VisuMax femtosecond laser system was used to perform small incision lenticule extraction to treat refractive errors. The laser was used to cut a refractive lenticule intrastromally to correct myopia and myopic astigmatism. The lenticule was then extracted from the stroma through a 3.0 to 5.0 mm incision. Outcome measures were corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), and manifest refraction during 6 months of follow-up. Corneal topography and ocular wavefront aberrations were also measured.
The study enrolled 51 eyes of 41 patients. The mean spherical equivalent was −4.87 diopters (D) ± 2.16 (SD) preoperatively and +0.03 ± 0.30 D 6 months postoperatively. Refractive stability was achieved within 1 month (P<.01). Six months after surgery, 79% of all full-correction cases had a UDVA of 20/25 or better. The 6-month postoperative CDVA was the same as or better than the preoperative CDVA in 95% of eyes. Two eyes lost 1 line of CDVA.
All-in-one femtosecond refractive correction using a small incision technique was safe, predictable, and effective in treating myopia and myopic astigmatism.
