Corneal astigmatism following cataract extraction.
The changes in corneal curvature in the first six months after cataract extraction were studied by performing sequential keratometry on a group of 57 patients. 8/0 Virgin silk interrupted sutures were used for the closure of corneoscleral incisions, and 10/0 monofilament tied in double running (bootlace) or single running (continuous) fashion was used for corneal wound closure. A high degree of...
متن کاملCorneal astigmatism after micro-incision cataract operation.
GOALS To evaluate the effect of micro-incision (2.2 mm) and small-incision (3.0 mm) coaxial phaco-emulsification on surgically induced astigmatism (SIA). METHODS Cataract patients (n = 60, 60 eyes) were randomized into two groups: 30 eyes in the 2.2-mm incision group, 30 eyes in the 3,0-mm group. Phaco-emulsification was followed by intraocular lens implantation via the Monarch II injector wi...
متن کاملPrevalence of Preoperative Corneal Astigmatism in Patients Undergoing Cataract Surgery at Mettapracharak Hospital, Thailand.
OBJECTIVE To describe and analyze the demography and distribution of preoperative corneal astigmatism in patients undergoing cataract surgery at Mettapracharak Hospital. MATERIAL AND METHOD The medical records of consecutive patients who had cataract surgery between October 1, 2010 and September 30, 2011 at Mettapracharak Hospital were retrospectively reviewed and analyzed. Patient demographi...
متن کاملContribution of posterior corneal astigmatism to total corneal astigmatism.
PURPOSE To determine the contribution of posterior corneal astigmatism to total corneal astigmatism and the error in estimating total corneal astigmatism from anterior corneal measurements only using a dual-Scheimpflug analyzer. SETTING Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA. DESIGN Case series. METHODS Total corneal astigmatism was calculated using ray trac...
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...
