purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

Pre-operative keratometry measurement of the subjects was done in 80 children with bilateral congenital cataract below 15 years who had undergone pediatric cataract surgery. The objective of the study was to evaluate the average keratometry reading in Nepalese children with bilateral cataract. The keratometry reading was taken under general anesthesia with the Nidek Auto Keratometer, model KM-5...

To study the keratometry of Indian pediatric eyes, effect speculum on reading, concordance hand held and automated unilateral bilateral cataract IOL power calculation. This was conducted as a cross- sectional observational 101 eyes children in age range 41 post-conceptional weeks to 144 months. All cooperative patients were subject followed by using keratometer with without speculum. Hand docum...

purpose: to evaluate agreement between galilei, orbscan ii, and placido disk-based topography in terms of keratometry readings, and anterior and posterior elevation. methods: in this prospective comparative study, 184 eyes of 92 keratorefractive surgery candidates were evaluated with galilei, orbscan ii, and placido disk-based topography. keratometry readings and anterior and posterior elevatio...

INTRODUCTION The biometric parameters of the eye are measured for the calculation of the intra ocular lens power to be used in cataract surgery. OBJECTIVE To report the keratometry reading, axial length and intra ocular lens power used for eyes operated for cataract in Karnali Zone, Nepal, and to compare these findings with those reported in other similar studies. SUBJECTS AND METHODS The d...

PURPOSE To compare the accuracy of central true net corneal power (cTNP) and mean true net corneal power (mTNP) of the Pentacam system to give a keratometry (K) reading for calculating IOL (intraocular lens) power in eyes following refractive surgery. METHODS Refraction, an automated K-reading (Km), cTNP and mTNP were measured for 15 eyes that required cataract surgery and had previously unde...

PURPOSE To assess subjective visual function after corneal collagen crosslinking (CXL). SETTING Cornea and refractive surgery subspecialty practice. DESIGN Prospective randomized controlled clinical trial. METHODS Patients completed a subjective questionnaire regarding visual symptoms administered preoperatively and 1 year after CXL. Patients ranked self-reported symptoms of photophobia, ...

INTRODUCTION Now-a-days, all techniques of cataract extraction are meant for giving the best uncorrected visual acuity and early post-operative rehabilitation. PURPOSE To compare astigmatism induced by the superior and temporal section in manual small incision cataract surgery (SICS) in the Indian population. MATERIALS AND METHODS One hundred and ten eyes were taken. Eyes having a steeper v...

the aim of this study was to evaluate the effect of mechanical implantation of myoring in keratoconic patients with high myopia. this study comprised 32 eyes of 32 keratoconic patients (14 males, 18 females) with high myopia. all underwent myoring (dioptex gmbh) implantation using mechanical dissection with a pocket maker microkeratome and completed three months of follow-up. the main outcome m...

Objective. This is prospective randomized control trial to compare the mean keratometric corneal astigmatism diopter power (not surgical induced astigmatism) among preop and one-month and three-month postop phacoemulcification of either a clear temporal corneal incision or a superior scleral tunnel Incision, using only keratometric astigmatic power reading to evaluate the difference between the...
