NCT ID: NCT06392607 Not yet recruiting - Myopia Clinical Trials

Euclid Phoenix Lens Design Trial 2

Start date: May 2024
Phase: N/A
Study type: Interventional

Lens wettability and subjective comfort of Euclid orthokeratology lenses with and without an enhanced coating will be compared in 50 children. Axial elongation will be monitored in pediatric patients who qualify and consent.

NCT ID: NCT06389916 Active, not recruiting - Myopia Clinical Trials

Euclid Phoenix Lens Design Trial

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

The "first fit" success rate of the current Euclid orthokeratology "MAX" lens design will be compared to that of the new Euclid orthokeratology MAX "Phoenix" lens design in 30 children.

NCT ID: NCT06353776 Completed - Cornea Clinical Trials

MicroPulse Transscleral Laser Therapy and Its Short-term Impact on Ocular Surface

Start date: May 3, 2023
Phase: N/A
Study type: Interventional

MicroPulse transscleral laser therapy (TLT) is proven to be effective in reducing intraocular pressure with minimal complications in either primary or secondary glaucoma. However, its impact on the human ocular surface remains unexplored. This study aims to bridge this gap by examining the clinical and histopathological effects of MicroPulse TLT on the ocular surface.

NCT ID: NCT06277349 Completed - Cataract Clinical Trials

Multifocal-toric IOL Compared to Multifocal IOL Combined With Limbal Relaxing Incisions for Correction of Moderate Astigmatism During Cataract Surgery

Start date: March 4, 2009
Phase: N/A
Study type: Interventional

The purpose of the present study is to compare the outcome of multifocal toric intraocular lens with standard multifocal lens plus incisional surgery in patients undergoing bilateral cataract surgery.

NCT ID: NCT06220578 Completed - Cornea Clinical Trials

Analysis of Topographic Corneal Parameters

Start date: January 1, 2023
Phase:
Study type: Observational

The Pentacam HR system (OCULUS) has been suggested to be one of the most sensitive instruments for corneal examination before corneal refractive surgery

NCT ID: NCT05759780 Recruiting - Skin Diseases Clinical Trials

OCT Vibrography for Biomechanical Properties of Tissues

Start date: August 19, 2023
Phase: N/A
Study type: Interventional

The overall goal of this study is to develop OCT Vibrography (aka OCT elastography) as a novel tool for measuring biomechanical properties of human tissues in vivo.

NCT ID: NCT05745220 Completed - Cornea Clinical Trials

Influence of Silicone Hydrogel Contact Lens Neophyte Wear on Corneal Sensitivity

CSCL
Start date: April 8, 2023
Phase: N/A
Study type: Interventional

Soft contact lenses can affect the ocular surface and sometimes cause intolerance. The aim of this study is to measure corneal sensitivity using the Swiss Liquid Jet aesthesiometer at baseline, after one and after six weeks, in novice daily contact lens wearers.

NCT ID: NCT05345652 Not yet recruiting - Keratoconus Clinical Trials

Evaluation Of Deep Anterior Lamellar Keratoplasty By Anterior Segment Ocular Coherence Tomography

Start date: May 1, 2022
Phase:
Study type: Observational

Investigators' research is concerned observing the post-operative anterior segment OCT changes throughout the post- operative follow up of the patient and relating to improve the visual outcome of the surgery which is the goal of surgery

NCT ID: NCT05298917 Completed - Cornea Clinical Trials

Influence of Silicone Hydrogel Extended Contact Lens Wear on Corneal Sensitivity

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

Soft contact lens wear reduces the amount of oxygen reaching the eye, which may have an influence on corneal sensitivity. The aim of this study is to measure corneal sensitivity with means of liquid jet esthesiometry at baseline and after 6 days of continuous, extended contact lens wear.

NCT ID: NCT05232539 Recruiting - Glaucoma Clinical Trials

Efficiency of Intraoperative Optical Coherence Tomography (iOCT)

Start date: May 2022
Phase: N/A
Study type: Interventional

Efficiency of Intraoperative Optical Coherence Tomography (iOCT) Hypothesis: The use of iOCT during surgery offers the advantage of a new view of the operating field, theoretically allows more precise performance and can also change decision-making mechanisms during surgery with more precise visual control of some surgical steps (incision adaptation, differentiation of healthy and pathological tissue, placement of the implant, graft, etc.) The disadvantage is the prolongation of the operation and thus the theoretical increase in possible complications related to the operation (bleeding, infection, patient subjective problems - pain, restlessness, poorer cooperation and the resulting other possible risks, such as unexpected patient movement). Aim: Determining the effectiveness of iOCT use in different types of eye surgery. Evaluation of advantages and disadvantages of using iOCT.
