Active clinical trials for "Hyperopia"

The purpose of this study is to evaluate the thickness accuracy of Laser-assisted in situ keratomileusis (LASIK) flaps created with the LenSx® Laser.

The purpose of this study is to compare the performance of the ACUVUE® ADVANCE® Plus lenses against ACUVUE® ADVANCE® lenses in the plus power parameters.

This DWCIE Study is a prospective cohort study of patients fit to the FDA approved and marketed lotrafilcon A (Ciba Vision, Air Optix Night & Day Aqua) soft contact lenses for daily wear (DW) with monthly disposal. 218 healthy myopic (nearsighted) or hyperopic (farsighted) patients with minimal or no astigmatism and no contraindications to DW lens use will be followed for 1 year. The primary outcome is the risk of development of a corneal inflammatory event (CIE) as defined by slit lamp findings and patient symptoms. The main exposure of interest is microbial contamination of study lenses.

This will be a prospective, single-center clinical trial of up to 50 eyes of subjects scheduled to undergo LASIK surgery requiring an initial corneal flap. Subjects will be screened for eligibility. Subjects will undergo LASIK surgery using the LenSx Laser to create the corneal flap prior to excimer laser treatment. Subjects will be evaluated intraoperatively to assess the ease of lifting the flaps, the stromal bed quality, and the amount of opaque bubble layer. All patients will be followed with routine vision exams for 3 months postoperatively to evaluate changes in visual acuity, manifest refraction, slit lamp examination, and endothelial cell counts.

The objective of this clinical study is to evaluate the safety and effectiveness of intrastromal implantation of the Allotex TCA for improving distance vision in hyperopic subjects. The overall objective with respect to visual outcome is to provide improved vision without the requirement of additional visual aids.

The purpose of this study is to investigate the variability of RNFL and macular thickness between myopia , hyper metropia and emmetropia

The primary purpose of the protocol is to evaluate the adaptive optics visual simulator to measure optical aberrations in hyperopic eyes. The study hypotheses are the: Ability to measure optical aberrations in hypermetropia. Knowledge of optical aberrations of the eye hyperopic. To adapt therapeutic management in optical aberrations measured.

To evaluate visual outcomes and patient satisfactory after PanOptix implantation in hyperopic cataract patients

The purpose of this study was to investigate the safety and efficacy of the Sauflon Clariti Monthly silicone hydrogel contact lenses with handling tint (Sauflon Pharmaceuticals Limited) by comparison with Air Optix Aqua silicone hydrogel lenses (Alcon Inc.) Subjects used OptiFree Replenish solution (Alcon Lboratories Inc.) for daily lens maintenance, care and storage.
