Filter by:This prospective randomized controlled trial will be conducted to investigate Clareon intraocular lens (IOL) stability in vitrectomy patients. The investigator plans to target the patients undergoing cataract surgery. A randomized study will be conducted with 2 arms, one with Clareon IOL versus a second arm using the Tecnis 1 In this non-inferiority study, the investigator will compare Clareon IOL from Alcon with the existing Tecnis 1 IOL from Precision Lens which is the commonly used intraocular lens in combined vitrectomy cases in Hong Kong.
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
In this retrospective case series, the feasibility of performing phacoemulsification using slit illumination in eyes with corneal opacity was assessed.
This prospective study included patients with primary angle-closure (PAC or primary angle-closure glaucoma (PACG) and visually significant cataract. Phacoemulsification with multifocal intraocular lens (MIOL) or monofocal IOL (mIOL) (patient preference) was performed. Collected data included best-corrected distant visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), and contrast sensitivity (CS) measured at spatial frequency 1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree (CPD) preoperatively, and at 2-6 months postoperatively. Preoperative and postoperative parameters were compared to evaluate the effect of MIOL on CS in eyes with PAC or PACG.
the investigators will compare between the endothelial cell loss after phacoemulsification and extracapsular cataract extraction in management of senile cataract
Despite the advantages already demonstrated by FLACS, these surgeries still require ultrasonic devices for fragmentation of the lens. The ultrasonic energy used during phacoemulsification may induce complications such as reduction of endothelial cells and corneal edema. In this sense, it would be beneficial to develop surgical techniques that eliminate the need for ultrasound. The group of surgeons of Alfredo Tranjan Ophthalmic Center, recently developed a surgical technique of cataract that optimizes the use of the laser, eliminating the need for ultrasound during the surgical procedure. Thus, the crystalline fragmentation process does not involve ultrasound being performed by the laser itself. It is expected that this procedure will reduce the complexity of cataract surgery, and be safer in terms of potential corneal lesions. The present study intends to evaluate the benefit and safety of FLACS without use of ultrasound (USFREE), compared to traditional phacoemulsification surgery using ultrasound in patients with senile cataract. In this sense, it is intended to primarily compare the volume of balanced saline solution (BSS) between surgeries.
