NCT ID: NCT06109636 Completed - Clinical trials for Corneal Biomechanics

Correlation Analysis Between Corneal Biomechanics and Anterior Segment

Start date: March 4, 2023
Phase:
Study type: Observational

Evaluation of the ciliary muscle thickness, area, and anterior chamber angle, as well as anterior sclera thickness in subjects, to investigate the relationship between these measurements and corneal biomechanics. Clarify whether aqueous humor displacement, anterior sclera, and ciliary muscles influence the assessment of in vivo corneal biomechanics.

NCT ID: NCT05377099 Completed - Clinical trials for Corneal Biomechanics

Evaluation of the Change in the DA Ratio, IR and SSI as Parameters of Corneal Biomechanics Post Different LVC Procedures

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

In the study, The Investigators will compare the participates' corneal biomechanical properties including: Deformation Amplitude ratio (Da Ratio) Integrated Radius (IR) Stress strain index (SSI) All measurements will be taken before and after 3 months of LVC.

NCT ID: NCT03990506 Completed - Keratoconus Clinical Trials

Photorefractive Intrastromal Crosslinking (PiXL) for the Treatment of Progressive Keratoconus

Start date: April 2, 2019
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the efficacy, safety and postoperative ocular discomfort by comparing individually customized Photorefractive intrastromal crosslinking (PiXL) for progressive Keratoconus. The study compares two different protocols, PiXL with corneal epithelium debridement (Epi-off) and PiXL without epithelium debridement in high oxygen environment (Epi-on), with the hypothesis that Epi-on gives less postoperative ocular discomfort.

NCT ID: NCT03500523 Completed - Pregnancy Clinical Trials

Corneal Biomechanical Properties in Pregnancy

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

57 eyes of 57 healthy pregnant women who were visiting Obstetrics and Gynecology department for routine examination and 26 eyes of 26 non pregnant control subjects who were at the first week of the menstrual cycle were enrolled in the study. All subjects had a detailed ophthalmologic examination including the best corrected visual acuity with a Snellen chart, slit- lamp biomicroscopic evaluation, and indirect fundoscopy. The biomechanical properties Corneal Hysteresis, Corneal resistance factor, corneal compensated intraocular pressure and Goldmann-correlated intraocular pressure values were measured with ORA (Ocular Response Analyzer, software version 1.02, Reichert, Inc.) Central corneal thickness was measured with a built-in ultrasonic pachymeter attached to the ORA device.Axial length , Anterior chamber depth , and keratometry readings were acquired with an ocular biometer (IOLMaster; Carl-Zeiss Meditec, Inc.) before CCT determinations had been taken. Results of these parameters were compared between pregnant group and healthy control group.
