effect of arcuate incision on post-keratoplasty astigmatism
this work is a report 0/9 cases ofarcuate incision for correction 0/astigmatism, after penetrating keratoplasty. plannings were based ojj corneal topography, and the first operation was always arcuate incision alone. 11,e secondary plans were based on refractive errors. the mean of preoperative astigmatism was 6d with the range of5 to 9/). after arcuate incision a/the graft-host interface in th...
متن کاملLong-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...
متن کاملKeratoplasty: Moving to the Front
Penetrating keratoplasty (PKP) has a long track record of high success rates compared to other tissue and organ transplantations. Despite the immunologic privilege of the cornea, the issue of immunological rejection cannot be overlooked and endothelial rejection is observed in up to 20% of eyes undergoing PKP. 1 Repeat keratoplasties after rejection are increasingly more prone to rejection and ...

متن کاملCorrection 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...
