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 کاملCataraCt Surgery aStigmatiC CorreCtion
By Eric D. DonnEnfElD, MD Astigmatic management is the step that most often keeps patients from achieving optimal visual quality after refractive cataract surgery. Residual astigmatism of 0.50 D and sometimes less may result in glare, symptomatic blur, ghosting, and halos. A recent study of 4,540 eyes of 2,415 patients showed that corneal astigmatism was present in the majority of patients unde...
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 کامل[Surgical correction of astigmatism during cataract surgery].
PURPOSE To evaluate the effect of peripheral limbar relaxing incisions (PLRI) in the reduction of the astigmatism during cataract surgery. METHODS We studied prospectively 103 eyes of 103 patients submitted to PLRI, using the Nichamim nomogram during cataract surgery by phacoemulsification. After the first and sixth month we analized the changes in astigmatism topography, induction of astigma...
متن کاملSurgical Correction of Astigmatism During Cataract Surgery
Naturally occurring (idiopathic) astigmatism is frequent, with up to 95% of eyes having detectable astigmatism. It is estimated that approximately 70% of the general cataract population has at least 1.00 D of astigmatism, and approximately 33% of patients undergoing cataract surgery are eligible for treatment of preexisting astigmatism.1,2 Today, cataract surgery is regarded as a refractive sur...
