Active clinical trials for "Cataract"

The investigators will investigate whether video-assisted informed consent is superior to routine discussion for cataract patients about risks, benefits and alternatives to receiving phacoemulsification cataract extract and intraocular lens implantation, and will determine whether video-assisted informed consent can reduce the work load of physicians.

This clinical study (non AMG/non MPG) is a contralateral, comparative, randomized, prospective, single-center, multi-surgeon, investigator masked study to investigate whether the femtolaser cataract surgery causes any significant differences in the resulting Intra Ocular Lens overlap (ΔROverlap) as compared to the conventional, manual continuous curvilinear capsulorhexis (CCC). The Intra Ocular Lens overlap (ΔROverlap) is defined as the difference between the Intra Ocular Lens center of mass to the capsulotomy aperture center of mass.

The purpose of this pilot feasibility study is to assess whether treating meibomian gland dysfunction (MGD) prior to cataract surgery helps promote meibomian gland function, visual quality and ocular comfort after cataract surgery.

This clinical trial compares two implantable devices intended to lower the pressure inside the eye of glaucoma patients. One of the two devices will be implanted immediately following cataract surgery and the placement of a posterior chamber intra-ocular lens.

With age, a human crystalline lens opacifies (cataract) disabling the eye in generating a clear, well contrasted image. The only therapeutic solution to this problem is surgical replacement of the crystalline lens with an intraocular lens (cataract surgery). In addition to the cataract, the person might suffer from pre-existing cormeal astigmatism. In cases of severe corneal astigmatism, the standard IOL might not provide the optimal result, and additional surgical procedures as Incisional Keratotomy or Limbal Relaxing Incisions might be required. BunnyLens TR IOL is an Aspheric Toric intraocular lens providing a precise, superior alternative to surgical treatment of pre-existing corneal astigmatism. The BunnyLens TR IOL is designed for micro-incision cataract surgery (MICS), through 1.8mm incisions. The aims of this study are to: Demonstrate a reduction in refractive cylinder compared to pre-operative corneal astigmatism Exceed monocular best corrected distance visual acuity results provided in ISO guidelines.

The study design will be a prospective study comparing laser-assisted cataract extraction cases and traditional manual phacoemulsification cases. All cases will be performed by faculty-supervised residents at Parkland Memorial Hospital. This study aims to examine visual acuity and complication rates in femtosecond laser-assisted cataract surgery compared to traditional manual phacoemulsification cataract surgery for the beginning surgeon. In addition, this study will assess the subjective novice surgeon experience and the patient experience in terms of expectations and results.

Prospective, non-randomised, open, controlled, single-center post-market clinical follow study about Micropure 1.2.3. and PODEYE intraocular lenses.

In a randomized clinical trial, 30 eyes with traumatic cataract after open globe injury with IOL implantation underwent early and 30 eyes underwent late cataract surgery. We excluded patients who were under 12-year-old. All patients were visited at 1week, 4 weeks , 12 weeks and six months after surgery. In each visit, patients were examined regarding visual acuity, intraocular pressure (IOP), anterior chamber inflammation, IOL position and posterior synechiae. In addition, posterior segment evaluation and funduscopy were performed. Intraoperative complication including posterior capsular rupture, anterior vitrectomy and zonulysis as well as the site of IOL implantation were documented and postoperative complications including raised IOP, anterior chamber inflammation, visual axis opacity, posterior synechiae, subluxation of IOL, IOL pigment deposition were listed.

Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). Implantation of the IOLs is bilaterally.

prospective, comparative (3 arms), randomized, multicentric clinical trial
