(B)Role of Pentacam in Cataract Surgery:-
ثبت نشده
چکیده
The Pentacam’s new densitometry software is not without limitations. A poorly dilated pupil interferes with the device’s sampling technology, and so eyes with pseudoexfoliation, trauma, and intraoperative floppy iris syndrome, for example, are problematic. Also, white cataracts block the system’s ability to sample the central nucleus. Nevertheless, comparison studies with the LOCS III system have shown that the Pentacam better predicts the amount of phaco energy needed to remove various grades of cataract. 29

Pentacam Keratometric Values Unreliable for IOL Power Calculation After Refractive Surgery To the Editor: We read with interest the article by Gonen et al,1 which appeared in the August 2012 issue of the Journal of Refractive Surgery, on their study comparing keratometric data from 200 patients evaluated for refractive surgery using four different devices—an automated keratometer (KR 8800 [Topc...

Background and Objective: Proper method and machine for corneal evaluation is an important factor in many anterior segment interventions. This study was performed to compare the mean keratometry (K) readings obtained with an IOL Master and Pentacam for intraocular lens power calculation in normal subjects with no history of refractive surgery. Materials and Methods: Mean K values were obtained ...
متن کاملAnterior Segment Parameters Using Pentacam and Prediction of Corneal Endothelial Cell Loss after Cataract Surgery
PURPOSE We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS Pentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber dept...
متن کاملThe Comparison of Central and Mean True-Net Power (Pentacam) in Calculating IOL-Power After Refractive Surgery
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...
متن کاملCorneal power measurements using scheimpflug imaging in eyes with prior corneal refractive surgery.
PURPOSE To evaluate the accuracy of central corneal power measurements by Scheimpflug imaging (Pentacam) for eyes that had corneal refractive surgery. METHODS This study comprised two groups: a pilot group of 100 eyes with prior hyperopic or myopic LASIK that did not have cataract surgery, and a test group of 41 eyes with prior radial keratotomy (RK) and cataract surgery. In the pilot group, ...
