Development of a nomogram for femtosecond laser astigmatic keratotomy for astigmatism after keratoplasty.
PURPOSE To develop a nomogram for femtosecond laser astigmatic keratotomy (AK) to treat post-keratoplasty astigmatism. SETTING Three academic medical centers. DESIGN Retrospective interventional case series. METHODS A review of post-keratoplasty femtosecond laser AK was performed. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, manifest refraction, and keratometry were r...
متن کاملNon-penetrating femtosecond laser intrastromal astigmatic keratotomy in patients with mixed astigmatism after previous refractive surgery.
PURPOSE To report the outcomes of the correction of mixed astigmatism with non-penetrating femtosecond laser intrastromal astigmatic keratotomy in patients with previous refractive surgery. METHODS One hundred twelve eyes that had low mixed astigmatism after excimer laser surgery, refractive lens exchange, or phakic intraocular lens implantation underwent intrastromal astigmatic keratotomy us...
متن کاملComparison between toric and spherical phakic intraocular lenses combined with astigmatic keratotomy for high myopic astigmatism
BACKGROUND To compare the outcomes of a toric phakic intraocular lens (PIOL) and a spherical PIOL combined with astigmatic keratotomy (AK) for the correction of high myopic astigmatism. METHODS This study enrolled patients with high myopic astigmatism, including 30 eyes (22 patients) that received a toric PIOL implantation (TICL group), and 32 eyes (24 patients) that received combined AK and ...
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 کاملeffect of relaxing incisions for post penetrating keratoplasty astigmatism on graft curvature
purpose: to evaluate changes in graft steepness after graft refractive surgery (grs) and to discover influential factors and a coefficient to predict the amount of postoperative shift. methods: keratoconic patients with history of penetrating keratoplasty (pkp) who underwent grs due to high post-pkp astigmatism were included. changes in mean keratometry after grs were evaluated to find possible...
