Filter by:The goal of this clinical trial is to evaluate two separate operating room cataract measuring tools in predicting the residual astigmatism (prediction error) in patients with corneal astigmatism. The main question it aims to answer is: Show the refractive predictability comparing the use of Operating Room cataract toric lens placement tools against the standard manual technique. Participants will be implanted with the TECNIS Toric II IOL Lens Model ZCU; the second eye, if applicable, is to be implanted within 45 days of the first-eye surgery. Researchers will compare two Operating Room cataract lens placement tools: the Zeiss CALLISTO vs. the Wavetec AnalyzOR to determine refractive predictability.
The objective of this study was to evaluate the clinical and patient reported outcomes after bilateral implantation of the AcrySof™ IQ Vivity™ Toric intraocular lens.
Subjects who had a bilateral age-related cataract surgery with the IOLs AT ELANA 841P and AT LISA tri 839MP will be contacted and invited to attend a postoperative visit more than one year after the surgery
The goal of this observational prospective clinical study is to learn about the clinical outcomes three months after binocular implantation of Asqelio Trifocal Toric IOL in 30 patients submitted to cataract surgery following standard clinical practice. The main questions it aims to answer are: How rotationally stable is the lens after implantation and how effective is in the correction of refractive astigmatism. Additionally, the visual performance at different distances will be assessed, as well as the patient-reported outcomes.
Direct comparison study between previous LASIK or non-LASIK cataract eyes, the performance between non-LASIK and LASIK patients were (i) Ophthalmic examinations: UDVA, CDVA and uncorrected near visual acuity (UNVA) (40cm) and (ii) Refractive prediction error: defined as difference between postoperative sphere and target refraction.
To evaluate the performance a new asferic monofocal intraocular lens (IOL) with higher order aspheric optic for far, intermediate, and near vision, in pediatric patients after monolateral cataract surgery.
To observe the effects of vitreous cavity Balanced salt solution (BSS) tamponade on the state of the lens and related parameters of the eye, and whether the changes of the above parameters are correlated with age, gender, diabetes or not, etc., so as to provide references for the diagnosis and treatment of related diseases and scientific research.
To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs in patients scheduled for bilateral cataract surgery.
This clinical study will assess the safety and performance of Intensity SL IOL, 1 year post operation. The study will also evaluate the patient satisfaction of the implanted patients.
This is a Prospective, single-center, randomized, controlled, paired-eye, single-masked clinical investigation to compare the efficacy and safety of FIDIAL PLUS (bacterial derived 1.8% sodium hyaluronate OVD) and IAL®-F (comparable animal derived 1.8% sodium hyaluronate OVD) while used during phacoemulsification cataract surgery.
