AIM To evaluate the use of accelerated corneal collagen cross-linking in the management of mild and moderate progressive keratoconus in comparison with conventional cross-linking. PATIENTS AND METHODS Prospective randomized interventional case-control clinical trial. A total 25 eyes of 18 patients were randomly divided into two groups: group A included 14 eyes that received accelerated collag...

T measurement of central corneal thickness (CCT) by pachymetry plays an integral part of the contemporary glaucoma workup. It is one of the relatively simple and straightforward ancillary tests performed today in the clinic. Clinicians have embraced this measure since the emergence of understanding its impact on the accuracy of tonometry such as Goldmann applanation tonometry (GAT). GAT, which ...

PURPOSE This study aimed to evaluate the effectiveness of phototherapeutic keratectomy (PTK) as an alternative treatment to keratoplasty using the Pentacam to assess depth of dense opacities. METHODOLOGY PTK was performed in eleven eyes of ten patients with superficial corneal opacities after assessment by Scheimpflug images of the Pentacam for central corneal thickness (CCT) and opacity leve...

Purpose. To determine the corneal biomechanical properties by using the Ocular Response Analyzer™ and to investigate potential factors associated with the corneal biomechanics in healthy myopic subjects. Methods. 135 eyes from 135 healthy myopic subjects were included in this cross-sectional observational study. Cornea hysteresis (CH), corneal resistance factor (CRF), cornea-compensated intraoc...

AIM To evaluate in vivo changes after therapy using autologous serum (AS) eye drops in Sjögren's syndrome (SS)-related dry eyes by confocal microscopy. PATIENTS AND METHODS In this study, 24 patients with SS-related dry eyes [12 in AS eye drop therapy and 12 in artificial tear (AT) therapy] and 24 healthy volunteers were recruited. Ocular Surface Disease Index (OSDI), central corneal thicknes...

PURPOSE To study the effect of mitomycin C (MMC) on the corneal regrowth after laser-assisted sub-epithelial keratectomy (LASEK). METHODS We performed a prospective, controlled, observer-masked study of 64 consecutive eyes scheduled to undergo LASEK to correct their myopia. The patients were divided into two age-matched groups, with group 1 including 32 eyes in which the ablation depth was ≤ ...

PURPOSE To obtain descriptive statistics of central corneal thickness (CCT) in a large population of normal eyes undergoing refractive surgery and study the relationship of 2 variables, age and refraction, with CCT. SETTING Cornea and Laser Eye Institute, Hersh Vision Group, Teaneck, NJ. METHODS The CCT of 5158 patients was measured using an ultrasound pachymeter. Age and preoperative spher...

PURPOSE To report visual outcomes and corneal biomechanical changes after femtosecond-assisted Intacs SK implantation in keratoconic eyes. METHODS This prospective interventional case series is comprised of 32 keratoconic eyes of 25 patients with mean age of 23.8 ± 5.4 years. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, refraction, manifest refraction spherical equivalent (...

PURPOSE To identify differences in corneal hysteresis (CH) and central corneal thickness (CCT) between healthy and glaucomatous patients. METHODS Retrospective observational study. One hundred and thirty-three eyes of 75 healthy and 58 glaucomatous patients were included. CH was measured in each patient using Ocular Response Analyzer. CCT was determined by ultrasonic pachymetry. For each pati...

Purpose. To describe the normative values of corneal endothelial cell density, morphology, and central corneal thickness in healthy Turkish eyes. Methods. Specular microscopy was performed in 252 eyes of 126 healthy volunteers (M : F, 42 : 84). Parameters studied included mean endothelial cell density (MCD), mean cell area (MCA), coefficient of variation (CV) in cell size, percentage of hexagon...
