The management of high postoperative astigmatism remains a major challenge for corneal refractive surgeons and various techniques have been evaluated.1 The recent introduction and development of femtosecond laser-assisted keratotomy could potentially combine a wide range of corrections with the accuracy and safety of laser treatment.2,3 Assessing the long-term visual and keratometric outcomes o...

PURPOSE To evaluate the effectiveness of arcuate incisions for correcting congenital, post-cataract, post-radial keratotomy, and post-trapezoidal keratotomy astigmatism. SETTING Buzard Eye Institute, Las Vegas, Nevada. METHODS In this retrospective study, 46 eyes of 29 patients had arcuate incisions to correct astigmatism. The average age of patients was 52 years. RESULTS Mean preoperativ...

A 33-year-old woman with irregular astigmatism 6 years after radial keratotomy (RK) for keratoconus was treated with implantation of a single intrastromal corneal ring segment (Keraring) using the femtosecond laser. The segment (0.150 mm thick with a 160-degree arc) was inserted in the steepest area (inferior) with no intraoperative or postoperative complications. Six months postoperatively, th...

We present a review of keratorefractive and intraocular approaches to managing residual astigmatic and spherical refractive error after cataract surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), arcuate keratotomy, intraocular lens (IOL) exchange, piggyback IOLs, and light-adjustable IOLs. Currently available literature suggests that laser vision correc...

Abstract Background To evaluate clinical outcomes after full-thickness astigmatic keratotomy (FTAK) combined with small-incision lenticule extraction (SMILE) in eyes high astigmatism. Methods This study comprised 75 of 43 patients over 4.0 diopters (D) astigmatism who were treated SMILE FTAK. Visual acuities and refractive measurements evaluated at 1 month FTAK, 1, 6, 12, 24 months SMILE. Vecto...

UNLABELLED Purpose. To describe a case of 3 refractive procedures performed in one eye over 2 decades. Methods. CASE REPORT Results. A 41-year-old patient presented for refractive surgery evaluation. His ocular history includes bilateral radial keratotomy performed 21 years ago for moderate myopia: spherical equivalence of -4.25 D bilaterally. Postoperative uncorrected visual acuity (UCVA) wa...
