Corneal Refractive Surgery

Abstract Cataract is the leading cause of blindness worldwide, and advanced cataract techniques such as femtosecond laser-assisted cataract surgery (FLACS) have been commercially available. Corneal refractive surgery (CRS) is one of the most popular surgeries for the correction of refractive errors. CRS changes the cornea not only anatomically but also pathophysiologically. However, there has been no clinical research analyzing the refractive and safety outcomes of FLACS after CRS. The aim of this study is to evaluate whether FLACS after CRS is more effective and safe than conventional PCS. Participants with a previous CRS history who underwent FLACS or conventional PCS were included in this study. The visual outcomes and the refractive outcomes including refractive, corneal, and ocular residual astigmatism were compared. The safety outcomes were then studied intraoperatively and postoperatively. A total of 102 patients with age-related cataract were enrolled. At 3 months postoperatively, UCVA, BCVA, and predictive error were not significantly different between the FLACS and conventional PCS groups. Reduction of refractive astigmatism was higher in FLACS. Postoperative ORA was significant lower in FLACS. Reduction of ORA was higher in FLACS. The intraoperative and postoperative complications were also not significantly different between the two groups. FLACS was found to be effective in patients with a previous history of CRS in terms of vision and refractive outcomes and was free from adverse effects. The competitive edge of FLACS in postoperative ORA, with the reduction of refractive astigmatism and ORA, may provide better visual quality than conventional PCS.

Abstract Background Femtosecond laser corneal refractive surgery is generally considered safe and effective; however, this procedure is rarely associated with severe allergic reactions. We reported a rare case of hypersensitivity reactions which caused bilateral peripheral corneal infiltrates after femtosecond laser small incision lenticule (SMILE) surgery in a man with a history of fruits allergy. Case presentation Here we report the case of a young man who developed white, ring-shaped bilateral peripheral infiltrates that appeared 1 day after an uneventful SMILE surgery. The overlying corneal epithelium was intact; the infiltrate was negative for bacterial culture, but high titers of immunoglobulin E was demonstrated in the blood. Symptomatically, a clinical diagnosis of sterile corneal infiltrates was made, and the patient was treated with topical and systemic steroids. The infiltrates were immunogenic in origin, which may be caused by the contact lenses used for suction duration in surgery. It resolved without corneal scarring in the subsequent months following steroid treatment. The patient’s visual acuity improved. Conclusions When patients with a history of allergy who aim to perform corneal refractive surgery, surgeons must consider possible hypersensitivity reactions after treatment. More studies are needed to clarify the relationship between contact glass used in femtosecond laser corneal refractive surgery and IgE mediated hypersensitivity reactions.

Abstract Background: To comparatively evaluate of the visual and refractive outcomes after small-incision lenticule extraction (SMILE), femtosecond laser-assisted in situ keratomileusis (FS-LASIK), and transepithelial photorefractive keratectomy (T-PRK) surgery.Methods: This was a retrospective, case-series, non-blinded clinical study. Consecutive eligible patients underwent SMILE, FS-LASIK, and T-PRK at the Department of Ophthalmology of Peking Union Medical Hospital, a tertiary referral center. All myopic patients were treated with corneal refractive surgery (SMILE, FS-LASIK, and T-PRK) using the VisuMax (Carl Zeiss Meditec AG, Jena, Germany) 500-kHz femtosecond laser system and the Amaris 750S excimer laser platform (SCHWIND eye-tech solutions, Kleinostheim, Germany). Visual and topographic astigmatism changes at 6 months were the main outcome measure. Secondary outcomes were the efficacy index at 1, 3, and 6 months postoperatively.Results: We recruited 75 consecutive patients (mean age, 27.88 ± 5.76 years; 68% women; all Asian) with no significant differences between groups in terms of preoperative demographic data, except in preoperative spherical equivalent (SE) (-5.54 ± 1.86 D, -5.64 ± 1.66 D, and -3.78 ± 1.30 D, respectively; P<0.001), astigmatism (1.24 ± 1.62 D, 1.16 ± 0.75 D, and 0.72 ± 0.42 D, respectively; P=0.008), and residual bed thickness (313.08 ± 32.18 μm, 427.59 ± 30.69 μm, and 427.09 ± 41.07 μm, respectively; P<0.001). A superior efficacy index was shown in SMILE and FS-LASIK compared to T-PRK 1 month after surgery.Conclusions: The results from this retrospective, non-blind, case-series clinical study suggest that all of the corneal refractive surgery options are safe and effective. However, while SMILE and FS-LASIK procedures have equal visual outcomes, they have superior efficacy index values in the early postsurgical period.

Purpose. To assess the incidence of central serous chorioretinopathy (CSCR) following laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK).Methods. A chart review was performed to identify all patients with CSCR and a previous history of LASIK or PRK.Results. Over the 6-year study period, 1 of 4,876 eyes which had LASIK or PRK at the Moran Eye Center was diagnosed with CSCR. One other patient was referred from an outside center, developed CSCR symptoms one month after PRK. Both patients were managed conservatively with a final visual acuity of 20/20 or better. All other patients presented 4 or more years after refractive surgery.Conclusions. We report the first 2 CSCR cases developing within one month after PRK. The low incidence argues against a causal association. Topical corticosteroids or anxiety may elevate cortisol levels presenting therapeutic challenges for the management of CSCR after PRK or LASIK.

Corneal Incisions

This article describes the current status of the femtosecond generated arcuate incision to correct corneal steepening. It covers the history of the surgical correction of astigmatism and describes the entrance of the femtosecond laser into modern corneal and cataract surgery. The process of photodisruption is explained as are the current indications for use of the femtosecond laser to make corneal incisions. A detailed narrative for programming the laser to perform arcuate incisions is included. Nomograms are referenced, and advantages over bladed incisions are described. A case is presented to show the use of these incisions in clinical practice. Finally, future developments are contemplated.
