OBJECTIVE To assess intraocular lens (IOL) power calculations in patients undergoing cataract surgery after excimer laser photorefractive keratectomy (PRK) for myopia. METHODS Four eyes of two patients underwent phacoemulsification with IOL implantation after PRK for myopia. The estimated refractive error that would have been induced had the IOL predicted for emmetropia been implanted was cal...

INTRODUCTION Keratometry forms an important component of the biometry for a calculation of the intraocular lens power and selecting a contact lens' parameters. OBJECTIVE To investigate the agreement between three different keratometers commonly used in an ophthalmology clinic. MATERIALS AND METHODS In this prospective study, keratometry was performed using an IOL Master (IM), a manual kerat...

AIM To determine the induced corneal astigmatism by measuring the changes in manual keratometry and computerised corneal videokeratoscopy up to 1 year following small flap trabeculectomy (microtrabeculectomy). METHOD A prospective study of a case series of small flap trabeculectomy procedures performed at the 90 degree meridian on 16 eyes of 16 patients, all followed to 1 year postoperatively...

PURPOSE To compare keratometric measurements using a Javal type manual keratometer with IOLMaster in eyes undergoing photorefractive keratectomy (PRK) for myopia. METHODS In this comparative case series, we studied patients aged 21 to 27 years scheduled for myopic PRK. Keratometry was performed preoperatively and three months after the procedure using a Javal type manual keratometer and the I...

Material and Methods: The study was conducted in the Department of Ophthalmology, Khyber Institute of Ophthalmic Medical Sciences (KIOMS), Postgraduate Medical Institute (PGMI), Hayatabad Medical Complex (HMC), Peshawar. In this study evaluation of 150 eyes of 134 patients were included in this study. Cataract surgery was performed in all cases by manual sutureless small incision technique. Pat...

purpose: to measure corneal power using different methods to assess agreement between these methods among patients who underwent photorefractive keratotomy. methods: in this prospective comparative study, keratometry was measured in 66 eyes of 33 refractive surgery candidates using manual keratometry (kr), conventional topography average central corneal power (accp), galilei total corneal power...

PURPOSE To compare the visual, refractive, keratometric, topographic, and pachymetric outcomes of corneal collagen cross-linking (CXL) for progressive keratoconus following epithelial removal by transepithelial phototherapeutic keratectomy (PTK) or manual debridement. METHODS In this analysis, 339 eyes (78% male, 22% female) that had undergone CXL following manual epithelial debridement (n = ...

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...
