Central corneal thickness in high myopia.

PURPOSE To examine if central corneal thickness (CCT) is different in emmetropia and high myopia. METHODS 57 emmetropic subjects (0 to + 1.5 D) and 48 high myopes (all more than - 6 D in spherical equivalent refraction) were studied. CCT was measured by a Haag-Streit Optical Low-Coherence Reflectometry (OLCR) pachymeter, a recently developed high precision pachymeter with a standard deviation...

Posterior Corneal Characteristics of Cataract Patients with High Myopia

PURPOSE To evaluate the characteristics of the posterior corneal surface in patients with high myopia before cataract surgery. METHODS We performed a cross-sectional study at the Eye and ENT Hospital of Fudan University, Shanghai, China. Corneal astigmatism and axial length were measured with a rotating Scheimpflug camera (Pentacam) and partial coherence interferometry (IOLMaster) in a high-m...

Assessment of Corneal Densitometry in Rheumatoid Arthritis Patients

OBJECTIVES To evaluate corneal densitometry and anterior segment parameters of rheumatoid arthritis (RA) patients and compare these results with those of age-matched healthy control subjects. MATERIALS AND METHODS Anterior segment parameters and corneal densitometry of patients with RA and healthy control subjects were assessed by Scheimpflug corneal topography. For densitometry analysis, the...

Normal Values of Corneal Optical Densitometry Using Pentacam Scheimpflug Camera

Cornea is unique to its transparency. It has Peculiar feature of transmitting almost all the light passing through it. Corneal clarity dwindles with surgical or pathological insults i.e. infections, corneal dystrophies and degenerations [1]. This induced corneal haze impedes the light rays to pass which results in backward scattering of light [2]. Maintaining regular surveillance over resulting...

Phacoemulsification in high myopia.

OBJECTIVE To analyze the visual results of phacoemulsification in highly myopic eyes, to investigate the risk factors for poor postoperative visual acuity and to assess postoperative complications. METHODS This retrospective study reviewed the records of 209 eyes of 150 patients with high myopia who underwent phacoemulsification and foldable intraocular lens (IOL) implantation between January...
