“…While there appear to be no studies on femto-LASIK post-FLEK, there are many studies on LASIK after conventional PK with blade trephination. All of these studies have shown significant improvements in visual acuity, refractive astigmatism, and spherical equivalent, with minimal to no complications [5, 6, 18–23].…”

“…Among these procedures, femtosecond LASIK, or femto-LASIK, is the most preferred and most common post-PK corrective surgery [4, 5]. Its popularity stems from its ability to correct a wide range of refractive errors with reportedly better and more predictable visual recovery outcomes than other procedures [2, 6–8]. Complications are relatively low in incidence but include corneal perforation and scarring, flap-related issues, epithelial ingrowth, and graft-host junction dehiscence [2, 8, 9].…”

Purpose. To evaluate the safety and effectiveness of femtosecond laser-assisted in situ keratomileusis (LASIK) in the treatment of residual myopia and astigmatism following femtosecond laser-enabled keratoplasty (FLEK). Design. Retrospective case review. Methods. Chart review of all patients with prior FLEK who subsequently underwent femto-LASIK surgery after full suture removal was performed at the Gavin Herbert Eye Institute at the University of California, Irvine. A total of 14 eyes in 13 patients met this criterion, and their comprehensive examinations performed at standard intervals were reviewed. Main outcome measures include uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) expressed as the logarithm of the minimum angle of resolution (logMAR), manifest refractive astigmatism, and spherical equivalent. Results. From the preoperative visit to the 3 month visit, all 14 eyes significantly improved in UDVA (logMAR, 0.93 ± 0.23 to 0.44 ± 0.32, P=0.002) with no loss of CDVA (logMAR, 0.26 ± 0.19 to 0.18 ± 0.23, P=0.50). All 14 eyes showed significant improvement in manifest refractive astigmatism (4.71 ± 1.77 to 2.18 ± 1.45 diopters (D), P=0.003) and spherical equivalent (−2.57 ± 2.45 to −0.48 ± 0.83 D, P=0.0007). There were no flap or graft complications as a result of femto-LASIK. Conclusions. Our findings suggest that femto-LASIK on eyes with prior FLEK is safe and effective in improving visual acuity and reducing residual astigmatism.

“…18 Both microkeratome 19,20 and Femto-LASIK have been shown to be effective in the correction of post-PK ametropia, but Femto-LASIK offers several benefits that include more predictable flap thicknesses and planarity, the possibility to choose the flap centration, and overall fewer intraoperative flap complications, especially in case of high corneal dioptric power. 21 Only a few papers investigate the results of this technique after Deep Anterior Lamellar Keratoplasty. Banu Toru Acar recently reported good refractive results after either 1-step or 2-step microkeratome LASIK procedures in a retrospective 13 eyes case series.…”

PurposeTo evaluate the refractive and visual results of one-stage laser-assisted in situ keratomileusis with femtosecond laser (Femto-LASIK) for the correction of residual ametropia after deep anterior lamellar keratoplasty (DALK).MethodsThis retrospective study included 13 eyes of 12 patients, who underwent corneal Femto-LASIK to correct refractive errors after DALK. IntraLase FS150 was used to create a lamellar flap and excimer laser ablation for refractive correction was performed using the Star S4 IR Excimer Laser in eight cases and the Technolas 217z Excimer Laser in Tissue Saving mode in five cases. Perioperative variables of interest included uncorrected (UDVA) and corrected (CDVA) distance visual acuities, manifest refraction and corneal topography.ResultsThe mean spherical equivalent preoperatively was -4.85±2.82 (range, -9.5 to 0 D). At the last visit the mean postoperative spherical equivalent (SE) was -0.44±0.67 D (P<0.05). The mean postoperative UDVA was 0.12±0.12 logMAR. There was a statistically significant increase in CDVA 6 months after Femto-LASIK (P<0.05). Intraoperative and postoperative complications did not develop in this series of eyes.ConclusionsCorrecting the preoperative manifest refractive error with Femto-LASIK led to a significant improvement in the UDVA and CDVA without surgical complications.
