Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography-Guided Repositioning: A Case Report. [PDF]

Clin Case Rep
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,

Repeatability of keratometry depending on tear film osmolarity. [PDF]

Acta Ophthalmol
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

Effect of Age on Pentacam Keratoconus Indices [PDF]

Journal of Ophthalmology, 2018
Purpose. To assess the effect of age on elevation and pachymetric Pentacam keratoconus (KC) detection indices, and the need to adjust normative values accordingly. Methods. In a retrospective study, 95 eyes of myopic normal subjects without KC were evaluated using the OCULUS Pentacam, with an age range of 17.4 to 46.8 years.

Postoperative Capsular Bag Distension Syndrome: Case Report of an Early Case Following Athalamia due to Vigorous Eye Rubbing. [PDF]

Case Rep Ophthalmol Med
Introduction Capsular bag distension syndrome (CBDS) is a rare complication of phacoemulsification, characterized by fluid retention in the capsular bag leading to reduced visual acuity, a myopic shift, and a risk of pupillary block. Case Presentation We report the case of a 65‐year‐old male who developed CBDS after rubbing his eye vigorously ...

Pentacam Indices in Photorefractive Keratectomy Surgery

Journal of Medicine and Life, 2020
Refractive eye surgeries are one of the most non-emergent ophthalmic surgeries due to the effect on the reduction of refractive errors, increasing visual acuity, enhancing the quality of vision, and indirectly increasing the quality of life of patients.
