Errors in supplementary toric IOL implantation (Sulcoflex toric, Rayner)

Ophthalmology Reports, 2015
In the article, the results of a combined surgical treatment method of induced astigmatism in a pseudophakic eye are presented. The authors describe an initial case of “wrong” supplementary toric IOL Sulcoflex (Rayner, Great Britain) position and its influence on aberrometric parameters.

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, Volume 104, Issue 5, Page e530-e537, August 2026.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

Insights into the rotational stability of toric intraocular lens implantation: diagnostic approaches, influencing factors and intervention strategies

Frontiers in Medicine
Toric intraocular lenses (IOLs) have been developed to enhance visual acuity impaired by cataracts and correct corneal astigmatism. However, residual astigmatism caused by postoperative rotation of the toric IOL is an important factor affecting visual ...
