femtosecond laser arcuate keratotomy for the correction of postkeratoplasty high astigmatism in keratoconus

Correction of high astigmatism using LASIK and arcuate keratotomy

We describe the case of a 47-year-old man who came to our center to be assessed for refractive surgery in 2007. The initial scan (instillation of 3 drops of cyclopentolate 1%) revealed a corrected distance visual acuity of 20/60 with +0.50 –9.50 × 10° in OD and 20/60 with +1.25 –9.50 × 165° in OS. We performed laser in situ keratomileusis (LASIK) in both eyes using a bicylindrical approach afte...

Effects of lamellar keratotomy on postkeratoplasty astigmatism.

AIM To determine the changes in postkeratoplasty astigmatism induced by lamellar keratotomy. METHODS A prospective, non-randomised comparative trial of patients undergoing a hinged lamellar corneal flap for treatment of significant astigmatism after penetrating keratoplasty. Uncorrected visual acuity, best corrected visual acuity, refraction, and corneal topography were assessed at 1 and 3 mo...

Long-term outcomes after mechanized arcuate keratotomy for the correction of astigmatism after keratoplasty.

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...
