Clinical Trials [233 Associated Clinical Trials listed on BioPortfolio]

A Comparison of PRK and LASIK for Correction of Myopia

The study compares the precision and accuracy of two laser refractive techniques, PRK and LASIK, for correction of nearsightedness between -6 and -8 diopters.

Comparison of LASIK and SBK

The objective of the study is to compare clinical outcomes from LASIK and SBK using FDA-approved laser technology on the same patient

Efficacy of LASIK Versus PRK in Asians With Mild and Moderate Myopia

Laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) are currently the 2 main refractive surgeries to correct myopia which are being performed worldwide, with more pa...

The Effect of Ablation Depth on Dry Eye After LASIK Treatment of Myopia

The study tried to find the relation between ablation depth and degree of dryness after LASIK treatment of myopic patients

Evaluation of Epi-lasik in U.S. Army Personnel

The purpose of this study is to evaluate the safety and efficacy of Epi-Lasik in U.S. Army personnel who have naturally occurring myopia with or without astigmatism. The data from this co...

Flap-Lift LASIK 10 or More Years After Primary LASIK.

To evaluate the safety and efficacy of flap-lift LASIK performed 10 or more years after the original LASIK procedure.

Contrast Sensitivity After Wavefront-Guided and Wavefront-Optimized PRK and LASIK for Myopia and Myopic Astigmatism.

Pre-cut post-LASIK/PRK donor corneas for use in endothelial keratoplasty: potential impact of post-cut morphology on visual outcomes.

To evaluate the accuracy, complication rates, cut quality, and degree of induced hyperopic shift of eye bank-prepared post-LASIK/PRK donor corneas compared to that of non-post-LASIK/PRK donor corneas.

Comparison Between Q-Adjusted LASIK and Small-Incision Lenticule Extraction for Correction of Myopia and Myopic Astigmatism.

To compare Q-adjusted femtosecond-assisted laser in situ keratomileusis (FS-LASIK) and small-incision lenticule extraction (SMILE) in terms of safety, efficacy, and predictability, as well as in terms...

Outcomes of Re-treatment by LASIK After SMILE.

To report the outcomes of LASIK re-treatments after small incision lenticule extraction (SMILE).

Medical and Biotech [MESH] Definitions

Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.

Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.

A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.

Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility.

A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
