Clinical outcomes of combined presbyopia and astigmatism correction following hydrophilic trifocal toric intraocular lens implantation in cataract patients: a prospective clinical study.
Most patients achieved spectacle independence for far vision after trifocal toric intraocular lenses implantation.
Clinical outcomes of combined presbyopia and astigmatism correction following hydrophilic trifocal toric intraocular lens implantation in cataract patients: a prospective clinical study.
Presbyopia and corneal astigmatism frequently coexist in cataract patients, reducing visual quality and increasing spectacle dependence.
Toric trifocal intraocular lenses (intraocular lenses) aim to address both conditions simultaneously.
This prospective, single-center, non-comparative clinical investigation included 28 eligible cataract patients with corneal astigmatism (1.00-6.00 D) who underwent bilateral implantation of the Liberty 677MTY trifocal toric intraocular lenses.
nearly all patients saw distant objects clearly without needing glasses
The Liberty 677MTY intraocular lenses demonstrated significant improvements (p < 0.05) in uncorrected and distance-corrected visual acuities and subjective refractive cylinder, with stability over time.
Intraocular lenses alignment was stable through follow-up, with mean signed and absolute rotations of < 2° and < 5°, respectively.
Based on patient-reported outcomes 89% rated satisfaction as high, and 83% reported mild or no difficulty with visual disturbances.
Safety analysis revealed one Nd: YAG-treated PCO case (1.61%) and no other intraocular lenses-related adverse events.
This study provides a detailed evaluation of the Liberty 677MTY trifocal toric intraocular lenses, integrating real-life binocular visual experience with comprehensive monocular assessments.
The lens demonstrated predictable refractive outcomes, excellent rotational stability, and consistently high-quality vision across all distances, with strong patient satisfaction.
Classified as full range of field smooth by monocular defocus curve analysis, the lens offers continuous functional vision.
