Piggyback toric IOLs in complex cases

This study evaluates the outcome of toric sulcus fixated lenses (MS 614/714 TPB (Human Optics, Germany) in 21 eyes with high astigmatism. The cases included previous penetrating keratoplasty (n=15), post cataract surgery astigmatism (n=3), rotation of in-the-bag toric IOL (n=1),...

Toric intraocular lens rotation related to the capsulorrhexis

The risk factors for postoperative rotation in the early post-operative period; a longer axial length, younger patients, and with the rule astigmatism as described by Miyake T et al. (JCRS 2014) in a case series of six eyes. This letter...

Aspheric toric IOL implantation and LRI in eyes with cataracts and astigmatism

This is a prospective study from a single unit to compare the visual outcome of aspheric toric intraocular lens (IOL) implantation and limbal relaxing incisions (LRI) for management of coexisting age-related cataracts and astigmatism. Sixty eyes of 60 patients with...

FSAK versus toric IOL implantation for correcting astigmatism in cataract patients

Nine studies of 590 patients were retrieved from the Ovid-Medline, EMBASE, Cochrane register of controlled trials and Scopus which compared femtosecond laser-assisted astigmatic keratotomy (FSAK) and toric IOL for astigmatism correction in cataract patients. The trial sequential analysis was used...

The rate of realignment of two toric monofocal intraocular lenses (IOL)

This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...

At least 70 percent of cataract patients could benefit from toric IOL

More than two-thirds of cataract patients could benefit from toric intraocular lenses (IOL), according to findings presented at 100% Optical. Consultant ophthalmologist Nigel Kirkpatrick set out how astigmatism is a significant issue for cataract surgery patients during a main stage...

Astigmatism correction in cataract surgery: Why are we still hesitating?

Toric spectacle lenses were first described in 1847 by George Biddell Airy, and their adoption was, presumably, gradual at that time. Today, correction of astigmatism with glasses is routine. In a recent survey, 87.2% of spectacle prescriptions contained at least...

The results of the last survey Feb21

Once again, I am grateful for the responses and read the results with interest. I am always surprised by the amount of practice variation I see. I fully accept there is art in what we do and there is no...

Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...

A look into the IOL space

Advances in the design and performance of intraocular lenses (IOLs) continue to be driven by demand for better outcomes, presbyopia correction and spectacle independence, alongside a better understanding of the dynamics of the crystalline lens, newer theories of accommodation and...

Topography-guided photorefractive keratectomy in the treatment of corneal scarring

This study reports the outcome of topography-guided photorefractive keratectomy (TG-PRK) in the treatment of patients with corneal scarring. A retrospective case series including six eyes of six patients with corneal scarring and irregular astigmatism who underwent topography guided PRK. The...

Pupil abnormalities after orbital surgery

This is a retrospective review of 287 patients who underwent removal of an orbital cavernous haemangioma (cavernous venous malformation), to ascertain the incidence of surgically induced pupillary abnormalities. Forty-four patients had lesions removed from the anterior or extraconal orbit, none...
