Active clinical trials for "Cataract"

The purpose of this study is to evaluate the visual quality and function of pseudophakic patients.

This study was set up to identify clinical outcomes including a refractive shift or change in IOL calculation accuracy and optical quality after Ophtec® capsular tension ring in the eyes without zonular instability.

To investigate the possible mechanisms by which cataract surgery aggravates meibomian gland dysfunction (MGD), the investigators evaluated the changes in tear cytokines and ocular surface parameters after cataract surgery according to the preoperative MGD grade.

The purpose of this study is to investigate the performance of LenSx® Laser in femtosecond laser-assisted cataract surgery (FLACS) in real-world medical practice in Chinese patients.

The purpose is to gauge the patients' level of comfort and anxiety for sequential cataract surgeries to assess if the second experience of cataract surgery differs from the initial experience.

To study correlation between postoperative corneal edema and endothelial cell loss after cataract surgery by microcoaxial phacoemulsification.

In the current study, the investigators analyzed the surgical RWD of 2,421 children with childhood cataracts from the Childhood Cataract Program of the Chinese Ministry of Health (CCPMOH) at the Zhognshan Ophthalmic Center and proposed data-based clinical experience for the timings of cataract extraction and IOL implantation.

This prospective, single center, non-comparative, 90-day follow-up, post-market clinical investigation of etafill in patients undergoing cataract surgery. The performance is measured by the preservation of endothelial cells measured by specular microscopy at the follow-up visit in comparison to baseline values.

Multifocal lens allow most patients to be spectacle-free after cataract surgery. Most studies published up-to-date have focused on visual acuity, but not on patient-reported outcomes. Since some patients with very good postoperative visual acuity report being very uncomfortable after surgery, the aim of this study is to evaluate if patient satisfaction is correlated with other outcomes, such as low-contrast visual acuity, contrast sensitivity, photic phenomena and ability to tolerate defocus. Patients who have undergone surgery with bilateral multifocal intraocular lens implantation will be carefully evaluated 3 months after surgery to try to determine the factors that correlate with patient reported outcomes as evaluated with the Catquest SF-9 questionnaire.

The purpose of prospective cohort study is to describe the developmental profile of refraction change in a large cohort of Chinese CC patients. The decisive factors to the range of myopic shift in unilateral CC appeared to be different from that in bilateral CC, indicating dramatic differences in the etiopathogenesis and refractive prognosis between bilateral and unilateral CC.
