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 ...

Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,

Accuracy of toric intraocular lens formulas with measured posterior corneal astigmatism of different orientations.

American journal of ophthalmology-glaucoma
PURPOSE To assess whether the use of measured posterior corneal astigmatism (PCA) values improves the prediction accuracy of toric intraocular lens power formulas, compared to predicted PCA values, when the orientation of the steep axis of PCA is non ...

Long-term outcomes of cataract surgery with toric intraocular lens implantation by the type of preoperative astigmatism

Scientific Reports, 2022
Surgical outcomes of toric intraocular lens (IOL) implantation for 8 years after surgery were analyzed. Data were retrospectively collected in 176 eyes of 176 patients before and 1 month, 1, 3, 5, and 8 years after phacoemulsification and implantation of

Repositioning of Vertical Implantable Phakic Contact Lens

Clinical Case Reports, Volume 14, Issue 9, September 2026.
Vertical orientation of Implantable Phakic Contact Lens. ABSTRACT Implantable phakic contact lens (IPCL) V2.0 has a special patterned hole on the leading left corner to ensure correct orientation and positioning. Incorrect orientation is an absolute indication for repositioning.

Intraocular light scatter as modeled through a stratified medium [PDF]

, 2001
Intraocular light scatter is modeled through a stratified medium. It is shown that the eye lens possesses properties of an interference filter. In conditions that may mimic opacification, as found with cataract formation, such a filter may have stop ...
