Toric intraocular lens implantation for cataract correction
Plate-haptic Toric Intraocular Lens (IOL) Implantation for Management of Cataracts
This tests whether toric intraocular lens implants with a haptic design help cataract patients achieve stable lens positioning and better visual quality.

What this trial studies
This observational study followed cataract patients who received toric intraocular lenses featuring a specific haptic design. Investigators recorded postoperative lens position and measures of clinical visual quality during follow-up visits. Standard ophthalmic examinations such as visual acuity, refraction, slit-lamp inspection and lens imaging were used to document outcomes. The intent was to describe the rotational stability of the lenses and how that stability relates to patient visual results.
Who should consider this trial
Good fit: Ideal candidates are adults with cataracts and suitable corneal astigmatism who are eligible for toric IOL implantation and lack major ocular comorbidities.
Not a fit: Patients with small pupils, zonular dehiscence, preexisting corneal pathology, glaucoma, uveitis, prior ocular trauma or surgery, or those experiencing severe intraoperative or postoperative complications may not benefit.
Why it matters
Potential benefit: If successful, this approach could provide more stable astigmatism correction and clearer vision after cataract surgery.
How similar studies have performed: Toric intraocular lenses are widely used and many studies report good refractive outcomes and acceptable rotational stability, though results depend on lens haptic design and surgical technique.
