Evaluation of the Safety and Efficacy of Corneal Cross Linking for the Treatment of Myopia.

43 Subjects (43 eyes) qualified for participation will undergo the required screening procedures to determine study eligibility. The surgical protocol involves applying riboflavin 0,22% to 0,25 % up to 20 minutes . Then, the eyes will be exposed to UVA (ultraviolet A) light with the KXL II system according to ...

Phase N/A

Ocular Imaging With Spectral Domain Optical Coherence Tomography

Assessment of macular thickness is important for the treatment and follow-up of a variety of ocular diseases. The introduction of optical coherence tomography (OCT) has enabled clinicians to reliably detect small changes in macular thickness and to quantitatively evaluate the efficacy of different therapeutic modalities. In this study using the ...

Phase N/A

Intrastromal Correction of Ametropia by a Femtosecond Laser

This study evaluates the intrastromal correction of ametropia with a femtosecond laser made by 20/10 PERFECT VISION. This laser generates a beam of ultrashort, infrared pulses which enables very precise cuts in the cornea. By these cuts lamellae of the cornea are separated locally, and in the consequence the curvature ...


A Prospective Safety and Effectiveness Study of the 500 Hz Technolas Perfect Vision Excimer Laser in Asian Eyes Using LASIK

This clinical study has been planned to evaluate the safety and effectiveness of the excimer laser treatment algorithms Proscan, Zyoptix and Supracor of the 500 Hz laser system for ametropia and/or presbyopia when performed on the cornea of virgin eyes.


Efficacy Study of Different Lens Treatments on Chinese Adolescent Myopia

Different lens treatments include normal spectacle lens, orthokeratology, and Myovision (a specially designed spectacle lens commercially available with peripheral defocus controlled as relative myopia). This study is to evaluate the efficacy of these three methods in controlling myopia progression. Until now, there is no sufficient clinical evidences to compare different ...

Phase N/A

A Study Assessing the Efficacy and Safety of DE-127 Ophthalmic Solution in Subjects With Mild or Moderate Myopia (APPLE)

To investigate the safety and efficacy of three concentrations of DE-127 ophthalmic solution when compared to Placebo in subjects diagnosed with mild or moderate myopia. To investigate the dose response of DE-127.


Topography-Guided Customized PRK Versus Q-value Adjusted PRK in Correction of Myopia With or Without Astigmatism

This study will include patients who will undergo PRK in both eyes, for each patient each eye will be randomly allocated to one of 2 procedures: topography-guided ablation in one eye (group I) and Q-factor customized ablation in the other eye (group II). Alcon/Wavelight Light Laser Technologie (GmbH, Erlangen, Germany) ...

Phase N/A

Safety and Efficacy Study of A Viscoelastic-free Method for Implantable Collamer Lens (ICL) Implantation

Implantable Collamer Lens(ICL) implantation has been proved to be an effective refractive option for surgical correction of high myopia. Currently, standard method utilizing the viscoelastic agent to fill and maintain the anterior chamber during the implantation, this requires an additional step to remove the viscoelastic agent at the end of ...

Phase N/A

Randomized Non-inferiority Trial Comparing SMILE and LASIK

Surgical correction for refractive errors may be performed by a number of procedures. Laser correction involves procedures such as EpiLASIK, LASIK or conductive keratoplasty, while lens based corrections involve the use of phakic intra-ocular lenses. Despite the emergence of other procedures, due to its fast visual rehabilitation and painless postoperative ...

Phase N/A

Variation of Orthokeratology Lens Treatment Zone (VOLTZ) Study

Orthokeratology (Ortho-k) treatment reduces the degree of myopia of the eye by flattening the central cornea. This central flattened zone is referred to as the treatment zone (TZ). Munnerlyn's formula describes the negative correlation between refractive correction and treatment zone size given a maximum ablation depth limited by the patient's ...
