Generally, there is a delay of 4 to 7 years in the diagnosis type 2 diabetes and about 20% patients would have already developed some micro vascular complications at time diagnosis. To study central corneal thickness (CCT) variation correlate with grades diabetic retinopathy an adult South Indian population. The was conducted on 184 eyes each T2DM duration more than 5 years. 98 males (53.26%) &...

PURPOSE To compare corneal pachymetry assessment using 4 measurement methods in eyes after laser in situ keratomileusis (LASIK) for myopia. SETTING Department of Ophthalmology & Visual Sciences, The Chinese University of Hong Kong, Hong Kong Eye Hospital, Hong Kong SAR. METHODS Fifty-two consecutive patients (103 eyes) who had LASIK for the correction of myopia had Orbscan II (Bausch & Lomb...

Objective: To determine the reliability and agreement of different optical devices in terms keratometry pachymetry measurements cross-linked (CXL) keratoconic eyes. Material Methods: Thirty-eight CXL-treated eyes were evaluated. Three repeated performed with Topcon KR-1 autorefractokeratometry, Sirius topography, Nidek AL-scan biometry RTVue anterior segment coherence tomography (AS-OCT). The c...

PURPOSE To report a novel method for pachymetry mapping of human precorneal tear film using Pentacam. METHODS Precorneal tear film is routinely undetected by Pentacam but could be well visualized with the aid of fluorescein. Twenty patients with dry eye and 20 age-matched control subjects with normal eyes were enrolled in this prospective study. The right eye of each subject was scanned once ...

purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thick...

AIMS To compare the metrics and surgical outcome when using Infiniti AquaLase and NeoSoniX cataract removal modalities. METHODS This prospective clinical study involved 50 patients with bilateral cataracts and lens removal using AquaLase in the right eye and NeoSoniX in the left eye. Best corrected visual acuity (BCVA), endothelial cell density and pachymetry were evaluted pre- and postoperat...

PURPOSE To compare ultrasound pachymetry and Orbscan II for measurement of central corneal thickness (CCT) in normal eyes. METHODS The current study was performed at Labbafinejad Medical Center (LMC), Tehran, Iran. Three hundred eyes from 150 healthy individuals referred for keratorefractive surgery were assessed first by Orbscan II and then by ultrasound pachymetry, and CCT values were recor...
