The purpose of this study is to evaluate the visual outcomes and patient satisfaction after bilateral implantation of the aspheric ReSTOR multifocal intraocular lens (IOL) and compare it to a historical control group of patients implanted bilaterally with the spherical ReSTOR multifocal IOL.
Randomized, controlled treatment with an intracanalicular dexamethasone (0.4mg) insert following cataract surgery with intraocular lens implant (IOL) combined with minimally invasive glaucoma surgery (MIGS), specifically iStent, iStent inject or KDB in patients with primary open angle glaucoma (POAG) or ocular hypertension (OHTN)
This study involves using both a device that seals the capsular bag (where the lens is located) allowing safer irrigation of the capsular bag and sodium chloride to irrigate the capsular bag during cataract surgery on children. The purpose of this study is to determine if the use of the device, Perfect Capsule, along with sodium chloride reduces the development of posterior capsule opacification (PCO), a possible complication of cataract surgery. PCO is the clouding of the rear portion of the natural membrane or capsule that holds the artificial lens. It requires additional procedures to correct the problem. Sodium chloride is not usually used during cataract surgery. It will be used to irrigate the capsular bag and remove any residual cells that contribute to the development of PCO. Perfect Capsule will prevent the sodium chloride from touching other parts of the eye. The goal of this study is to determine if irrigation with sodium chloride will lower the incidence of PCO after cataract surgery.
The purpose of this study is to evaluate the effect that placement and power of the AcrySof Toric has on post-operative visual acuity and spectacle independence for distance vision. This will be determined by comparing manifest refraction pre-operatively and post-operatively and by evaluating the rotational stability of the lens over time.
The objective of this study is to evaluate the uncorrected binocular distance, intermediate, and near visual acuities, and assess patient's spectacle independence and satisfaction in individuals undergoing bilateral cataract extraction that have received two different arms of near add design IOLs of the same diffractive multifocal model.
To evaluate the ability of the TRUEVISION 3D VISUALIZATION AND GUIDANCE SYSTEM FOR MICROSURGERY to provide the ophthalmic surgeon appropriate alignment, orientation and sizing information during cataract or refractive lens exchange surgery. Device images, safety results and surgeon questionnaire will demonstrate that the TrueVision system provides clear images to assist surgeons during LRI or capsulorhexis procedures.
The purpose of this study is to evaluate and compare the potential refractive outcomes using the Argos 1.5 biometer in the surgical planning for cataract extraction to that obtained from IOLMaster 700. Both devices are used as standard of care in surgical planning optimization for patients undergoing cataract surgery.
Phase 1 will be ambispective, multi-site, single arm study in age-related cataract patients with regular astigmatism, who were bilaterally treated with the LAL+ IOLs Phase 2 will be a prospective, randomized, unmasked, comparative, multi-site study with 90 days of follow up. Subjects will be randomized in a 1:1 manner to LAL+ or Clareon VIvity Toric IOLs.
Tecnis Symfony Optiblue EDOF IOL is the latest version of Tecnis Symfony IOL with a violet light filter (VLF), which blocks short-wavelength light and improves the quality of vision while minimizing visual disturbances. The present study aims to assess the visual outcomes at distance, intermediate, and near following cataract surgery and implantation of Tecnis Symfony Optiblue IOL in patients with retinal comorbidities.
The purpose of this study is to verify the post-market safety of the IC-8 Apthera IOL after the treatment of posterior capsular opacification (PCO), an expected complication related to IC-8 Apthera IOL implantation.
Prospective collection of data from medical records, multicenter, post-market clinical follow-up study.
Retrospective collection of data from medical records, multicenter, post-market clinical follow-up study.
The objective is to evaluate visual outcomes and patient satisfaction in patients with a history of myopic LASIK or PRK who will have completed cataract surgery with the Vivity IOL.
The goal of this observational study is to assess the effect of intraocular lens (IOL) movement in patients who have undergone Clareon® Vivity® IOL implantation. The main question it aims to answer is: Does an association exist between IOL movement and patient quality of vision? Participants implanted with Clareon® Vivity® and Vivity® Toric IOLs will be asked to do the following: * consent to participate in the study * allow researchers to access their personal medical records * undergo a series of tests to assess the position of their IOLs and quality of vision Researchers will assess participant examination results to determine whether an association exists between IOL movement and patient quality of vision.
The purpose of this study is to evaluate the long-term safety of the IC-8 Apthera intraocular lens (IOL).
This study is designed to determine how well patients with glaucoma can see following cataract surgery with a special type of lens called an extended-depth-of-focus (EDOF) lens. This lens is intended to reduced the patients need for glasses following cataract surgery. Patients will also undergo a minimally invasive type of glaucoma surgery using a special type of stent to reduce eye pressure, with the goal of better glaucoma control and the reduction in the need for medications to control eye pressure.
Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Different options are available. These options include: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocals and extended depth of focus (EDOF) IOLs. In a previous study that evaluated the visual outcomes of an EDOF IOL when combined with a multifocal IOL with a +3.25 D add in patients with or without astigmatism undergoing routine cataract surgery showed good outcomes with high patient satisfaction and less dependance on glasses for intermediate and near activities. As technology evolves, new lens models are available in the market. The purpose of this study is to evaluate the latest EDOF and a hybrid multifocal lenses when combined.
Most of the patients presenting for cataract surgery also have pre-existing corneal astigmatism which if left uncorrected can adversely affect visual and refractive outcomes after cataract surgery. Pre-existing astigmatism at the time of cataract surgery can be corrected by either corneal relaxing incisions or implantation of toric IOLs. While the safety and efficacy of these procedures are well established, there are various challenges associated with these techniques that surgeons need to overcome to achieve good outcomes postoperatively. The use of iris registration technology that automatically compensates for cyclotorsion has the potential to improve the alignment accuracy of CRI or toric IOLs. The Cassini Ambient and Catalys Femtosecond Laser incorporate this technology to help cataract surgeons accurately align toric IOLs on the intended axis of implantation or accurately place CRI on the intended meridian. The present study is aimed at evaluating the efficacy of astigmatism correction during femtosecond laser-assisted cataract surgery with Catalys femtosecond laser. The patients will either undergo iris registration guided CRIs or iris registration guided alignment of toric IOLs.
To evaluate visual outcomes, in-the-bag placement and patient satisfaction in patients implanted with either Clareon monofocal or Clareon monofocal toric IOLs with the Monarch IV inserter and targeted for emmetropia.
