[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...
متن کاملControl of astigmatism in cataract surgery.
A study is reported on cataract surgery, with intraocular lens implant, with measurement of the preoperative astigmatism and of the postoperative astigmatism over 28 weeks. Nine interrupted 10/0 nylon sutures are used to close a limbal section. Preoperative astigmatism is compensated for in the method of suturing by the placement of additional sutures. Postoperatively sutures are cut in line wi...
متن کاملFoldable toric intraocular lens for astigmatism correction in cataract patients.
PURPOSE To evaluate the results of AcrySof toric intraocular lens (IOL) (Alcon) implantation to correct preexisting astigmatism in patients having cataract surgery. SETTING Ophthalmology Service, Donostia Hospital, San Sebastián, Spain. METHODS This prospective observational study included 30 eyes of 15 consecutive patients with more than 1.00 diopter (D) of preexisting corneal astigmatism ...
متن کاملOptimizing the correction of low corneal astigmatism in cataract patients
RESULTS: Implantation of a toric IOL reduced the refraction astigmatism by 80%. Aberrations increased in all patients, but while astigmatic aberration decreased with toric IOLs, spherical aberration decreased with aspheric IOLs. The UCVA was better with toric and aspheric IOLs (0.1 logMAR), whereas the BCVA was statistically better with aspheric IOLs compared to spherical (p = 0.05). The CSF wa...
