Comparison of two strategies estimating surgically induced astigmatism in position prediction of toric IOLs in 2.2 mm cataract surgery.
Graefes Arch Clin Exp Ophthalmol
December 2024
Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, No. 83 Fenyang Road, Shanghai, 200031, China.
Purpose: To compare the precision of the arithmetic mean of surgically induced astigmatism (M-SIA) and the centroid of surgically induced astigmatism (C-SIA) in estimating SIA when predicting the power and axis of toric IOLs under different circumstances.
Methods: 120 eyes of 99 patients undergoing toric IOL replacement in a simple cataract surgery were included in the retrospective study. The predicted position of toric IOL was calculated by Z Calc online calculator and Barrett Toric Calculator with M-SIA (0.

Article Synopsis
- The study focuses on refractive changes observed in children aged 5 years who underwent cataract surgery with intraocular lens placement before age 2.
- It analyzed data from 96 children, comparing results between unilateral and bilateral cataract cases, as well as those operated on at different ages (1 to <7 months vs. 7-24 months).
- The findings indicated that children operated on between 1 to <7 months experienced significantly more refractive change compared to those operated on later, suggesting careful consideration is needed when selecting lens power and target refraction for younger patients.
The Multifocal Pathway: A Pilot Study of a Trainee-Led Multifocal Intraocular Lens Protocol in a Tertiary Referral Hospital in Australia.
Clin Ophthalmol
December 2024
Department of Ophthalmology, Westmead Hospital, Sydney, NSW, Australia.
Purpose: To develop a selection pathway to facilitate the use of multifocal intraocular lenses (mfIOLs) in cataract surgery in a public hospital setting.
Methods: A single-surgeon prospective cohort study in an Australian tertiary referral public hospital was conducted. A mfIOL selection pathway was designed and assessed.
In recent years, techniques for the secondary implantation of intraocular lenses have undergone significant further development. Despite the wide range of surgical indications, IOL dislocation and aphakia following complicated cataract surgery or other complicated intraocular procedures and trauma remain the most common reasons for secondary IOL implantation. In cases where it is not feasible to place the artificial lens in the capsular bag due to zonular weakness or insufficient stability of the capsular bag, the intraocular lens can be implanted in the anterior chamber or fixed in the ciliary sulcus, on the iris or on the sclera.

Clin Ophthalmol
November 2024
Sengi, Penniac, NB, Canada.
Article Synopsis
- The study evaluated visual outcomes and patient satisfaction up to 3 months after cataract surgery using hydrophobic acrylic intraocular lenses (IOLs).
- It included 28 patients and found excellent distance and intermediate visual acuity, with 98% of patients achieving good intermediate vision (20/25 or better).
- The results demonstrated high levels of patient satisfaction (88%) and successful lens delivery by surgeons (89% success rate), indicating the effectiveness of the Clareon IOL and Monarch IV system for cataract surgery.
