About

New extended depth of focus intraocular lenses (IOLs) are being used in a broader spectrum of patients than trifocal IOLs. The purpose of this study is to evaluate visual improvement after cataract surgery in patients with glaucoma or ocular hypertension undergoing simultaneous cataract surgery with i-Stent implantation with the implantation of a Vivity IOL. Results will be compared with a group of glaucoma or ocular hypertension undergoing isolated cataract surgery with Vivity implantation, as well as with patients with no pathology undergoing cataract surgery and Vivity implantation

Full description

The purpose of this study is to report in detail visual function and patient satisfaction, as well as the need for spectacle correction, in patients with glaucoma and ocular hypertension undergoing cataract surgery with bilateral implantation of an extended depth of focus IOL, the Vivity IOL. The study also seeks to determine if there are differences in the speed of visual improvement between patients undergoing isolated cataract surgery and patients undergoing simultaneous i-Stent implantation. Results will also be compared with a group of patients with no ocular pathology undergoing cataract surgery with Vivity implantation.

Patients will be asked to join the study once the type of surgery (isolated phacoemulsification versus phacoemulsification combined with i-Stent implantation) and the type of lens to be implanted (monofocal, EDoF, trifocal) has been agreed between ophthalmologist and patient. Therefore, inclusion in the study will have no influence on surgical indication.

Once informed consent has been signed, the patient will be included in the study.

Explorations specific for the study will be performed 3 and 12 months after surgery and include:

Defocus curves Contrast sensitivity Self-reported photic phenomena Need for spectacle correction Satisfaction measured with the Catquest SF9 questionnaire

Besides study-specific procedures, the following explorations which are standard of care will be performed one day, one week and one month after surgery:

Uncorrected binocular visual acuity for distance, intermediate and near distances Monocular distance corrected and uncorrected visual acuity Residual subjective refraction Slit-lamp examination Intraocular pressure and number of hypotensive drugs required Description of any intra- or postsurgical complications
