Purpose: To investigate the effects of pterygium excision with conjunctival autograft plus corneal polishing on ocular higher-order aberrations (HOAs) and to monitor the changes throughout the first postoperative year.
Methods: A total of 18 eyes of 16 patients with primary pterygium who had an indication for surgical excision were included in the study. All patients underwent a detailed ophthalmologic examination preoperatively and at the third and twelfth postoperative months.
Purpose: To investigate the effect of different sizes of pterygium on ocular aberrations along with corneal refractive changes, keratometry, and corneal topography.
Methods: Forty eyes of 34 patients who had different sizes of primary nasal pterygium and 40 eyes of 22 age- and sex-matched healthy subjects without a clinical diagnosis of pterygium or pinguecula were enrolled in this study. All patients underwent a measurement of uncorrected and best spectacle-corrected visual acuities, corneal topography, and ocular aberrations.
Purpose: The purpose of this study was to explore changes in ocular surface and tear function parameters in chronic hepatitis C at different stages of hepatic fibrosis.
Methods: Fifty-four patients with biopsy-proven chronic hepatitis C and 54 age- and sex-matched healthy control subjects without systemic hepatitis C infection were examined with the Ocular Surface Disease Index questionnaire, Schirmer with and without anesthesia, tear film breakup time, and scoring of ocular surface Lissamine green staining using modified Oxford and van Bijsterveld scoring systems and corneal fluorescein staining.
Results: Patients with chronic hepatitis C scored significantly worse than the control subjects on all parameters: modified Oxford scores of Lissamine green staining (5.
