Femtosecond laser enabled keratoplasty for advanced keratoconus.

Shivanna Y, Nagaraja H, Kugar T, Shetty R - Indian J Ophthalmol (2013)

Bottom Line: FLEK was found to have better outcome in view of better and earlier stabilization uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and better refractive outcomes with low astigmatism as compared with conventional PKP.Wound healing also was noticed to be earlier, enabling early suture removal in FLEK.Studies relating to FLEK have shown better results than conventional PKP, however further studies are needed to assess the safety and intraoperative complications of the procedure.

ABSTRACT

Purpose: To assess the efficacy and advantages of femtosecond laser enabled keratoplasty (FLEK) over conventional penetrating keratoplasty (PKP) in advanced keratoconus.

Materials and methods: Detailed review of literature of published randomized controlled trials of operative techniques in PKP and FLEK.

Results: Fifteen studies were identified, analyzed, and compared with our outcome. FLEK was found to have better outcome in view of better and earlier stabilization uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and better refractive outcomes with low astigmatism as compared with conventional PKP. Wound healing also was noticed to be earlier, enabling early suture removal in FLEK.

Conclusions: Studies relating to FLEK have shown better results than conventional PKP, however further studies are needed to assess the safety and intraoperative complications of the procedure.

Figure 3: Preoperative and postoperative uncorrected and best corrected visual acuity in patients who have undergone FLEK at 1, 3, 6, and 10 months

Mentions: In our experience, the mean uncorrected and best corrected visual acuity (UCVA and BCVA) [Fig. 3] preoperatively was 0.05 and 0.27 log Mar units, respectively. The UCVA more or less remained stable at follow-up visits at 0.32 (1 month), 0.34 (3 months), and 0.35 (6 and 10 months). However, the BCVA improved to 0.65 at 6 months which remained stable thereafter. There was early stabilization of UCVA and BCVA by 3 months.
