Early visual results with the rollable ThinOptX intraocular lens.

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Materials Science

Background:

• Cataract surgery involves phacoemulsification and intraocular lens (IOL) implantation.
• Foldable acrylic IOLs are commonly used, but newer designs aim to improve visual outcomes.
• Rollable IOLs with thin optics represent an advancement in IOL technology.

Purpose of the Study:

• To compare the clinical and visual outcomes of phacoemulsification with a rollable ThinOptX IOL versus a foldable acrylic AcrySof IOL.
• To assess visual acuity, contrast sensitivity, and postoperative complications in both IOL groups.

Main Methods:

• Prospective study comparing ThinOptX IOL (n=16 eyes) and AcrySof IOL (n=20 eyes) implantation after phacoemulsification.
• Assessment of distance and near visual acuities, contrast visual acuity, refractive status, and intraocular pressure (IOP).
• Anterior segment photography and specular microscopy were performed preoperatively and postoperatively.

Main Results:

• Both IOLs provided excellent best-corrected distance visual acuity (≥20/25 in all ThinOptX eyes and 90% of AcrySof eyes).
• Mean contrast acuity was significantly higher in the ThinOptX group compared to the AcrySof group.
• No significant differences in induced astigmatism, IOP, or corneal endothelial cell density were observed between the groups.

Conclusions:

• ThinOptX IOL implantation yields visual acuities comparable to AcrySof IOLs.
• The ultrathin properties of the ThinOptX lens may contribute to enhanced contrast acuity.
• Both IOLs demonstrated favorable safety profiles with no significant complications.
