31 Clinical Trials for Various Conditions
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, the visual outcomes of the EDOF Toric IOL were evaluated when both eyes were targeted for plano and when the non-dominant eye was set for a small residual myopic error (-0.50 D) or nanovision in patients with astigmatism. The nanovision approach, appeared to provide similar binocular acuity at distance and intermediate but better acuity at near. The purpose of this study is to evaluate 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.
In July 2016, the FDA approved an extended depth of focus (EDOF) IOL (Tecnis Symfony, Abbott Medical Optics) helping to improve the sharpness of vision at near, intermediate and far distances reducing the need of glasses after cataract surgery. It is available in both a non-toric version and a toric version for patients with astigmatism. The difference between this lens and the multifocal (MIOL) counterpart is that the EDOF, similarly to a monofocal IOL, has one focal point (elongated in the EDOF) while the multifocals have 2 focal points; therefore, having less of a halo and glare problem. Pivotal trial results where Symfony was compared to a monofocal IOL showed similar uncorrected distance visual acuity (UCDVA), better intermediate (77% vs. 34% 20/25 uncorrected intermediate visual acuity - UCIVA) and near vision (Symfony patients were able to read two additional, progressively smaller lines compared to the monofocal IOL).A One potential disadvantage of the EDOF IOL compared to a MIOL is the visual performance at near.B One option to deal with this potential shortcoming is to set the non-dominant eye for a small residual myopic error (-0.50 D)C what is referred to as nano-vision or mini mono-vision.
To evaluate the safety and efficacy of treating visually significant bilateral cataract with the newer technique of Immediate Simultaneous Bilateral Cataract Surgery (ISBCS) versus the conventional technique of Delayed Sequential Bilateral Cataract Surgery (DSBCS) in a select patient population.
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.
The purpose of this study is to describe rates of spatial distortions related to intraocular lens (IOL) misalignment for ACRYSOF® Single-Piece Toric NATURAL IOL Model SN60T9 when implanted bilaterally into the capsular bag following phacoemulsification in adult patients with bilateral cataract and regular corneal astigmatism. Subjects were implanted with the Model SN60T9 in the first operative (study) eye and either Model SN60T9 or Model SN60T8 in the second operative eye.
Iiopathic bilateral cataracts occur in many children with Cerebrotendinous Xanthomatosis (CTX) so the opportunity to use contact with health care providers in connection with pediatric cataract evaluation and treatment is a promising avenue for disease detection and prevention.
The objective of this study is to evaluate postoperative visual function in patients implanted bilaterally with the ReSTOR Aspheric Intraocular Lens (IOL).
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 prospectively evaluate the visual parameters in a series of patients after phacoemulsification cataract surgery in a series of patients bilaterally implanted with the AcrySof® ReSTOR® Aspheric +3.0 Intraocular Lens (IOL).
The goal of this pilot clinical trial comparing two different sedation approaches for cataract surgery is to assess patient satisfaction, the quality of recovery, and surgical outcomes as well as to evaluate the overall feasibility and acceptability of the study protocol for the purpose of planning a larger clinical trial. Participants will be asked to respond to several surveys throughout the study on their experience and to assess outcomes of interest.
Millions of people have undergone laser vision correction surgery and are motivated to continue with spectacle independence as they develop presbyopia (gradual loss of your eyes' ability to focus on nearby objects)and cataract. However, having a history of refractive surgery, poses challenges in the selection of the IOLs and can lead to visual outcomes that are unpredictable. Data from an international registry and single prospective study show that Vivity IOL provided effective distance, intermediate and near vision in eyes with previous LASIK with minimal effects on day vision associated with the surgery. The purpose of this study is to evaluate the clinical outcomes of post-myopic refractive surgery patients implanted with the Clareon Vivity/Vivity Toric lenses
Prospective, randomized, multicenter, multi-arm, subject and vision-assessor-masked, two stage study with Stage 1 as a three-arm initial enrollment period, followed by Stage 2 as a head-to-head study refined based on the Stage 1 data.
This study is a single center, ambispective study of visual outcomes after successful bilateral cataract surgery. Subjects will be assessed at least 3 months postoperatively at a single visit. Clinical evaluations will include administration of the AIOLIS and OSDI questionnaires, as well as measurement of visual acuities at distance, intermediate, and near.
To evaluate visual outcomes and quality of vision following bilateral implantation of the Clareon PanOptix intraocular lens (IOL) targeted for emmetropia.
The purpose of this study is to evaluate the AcrySof PanOptix Intraocular Lens (IOL) for binocular distance corrected near visual acuity (DCNVA) compared to TECNIS Synergy IOL. Presbyopia correcting diffractive intraocular implants (extended depth of focus, multifocal, and trifocal) provide cataract and refractive surgeons with an effective treatment means for allowing patients to experience increased spectacle independence post-cataract surgery.
The objective of this study is to assess the spectacle independence of patients receiving the AcrySof® Panoptix® Intraocular lens (IOL) after uneventful cataract surgery.

The purpose of this study is to compare the visual outcomes with bilateral implantation of Tecnis MF and ReSTOR intraocular lenses (IOLs) 6 months post cataract surgery.
The purpose of this study is to evaluate vision at different distances (far (13 ft), intermediate (2.0 ft) and near (13 to 15 in)) with and without the patient's glasses (if the patient wears them), range of vision (the difference between the farthest distance and the closest distance that the patient can comfortably read 20/25 of the near card), and patient satisfaction (how satisfied/happy is the patient with their vision) following bilateral implantation of different multifocal IOLs after routine phacoemulsification. The patients are being asked to participate in this study because you have had cataract surgery and have received one of the IOLs implanted: ReSTOR +4.0 D, ReSTOR +3.0 D, Crystalens, and/or ReZoom. The investigator in charge of this study is Dr. Helga Sandoval. This study is being conducted at Storm Eye Institute at the Medical University of South Carolina and will involve approximately 50 volunteers.
This study will involve up to 20 bilateral patients per surgeon. Patients will be assessed pre-operatively, and at subsequent visits (following the implantation of the intraocular lens in the second eye) at 1 week, 1 month, 3 months and 6 months post-operatively.
