Trifocal and Toric Intraocular Lenses: Options and Risks

Trifocal and toric intraocular lenses are lens options used in selected cataract or refractive lens procedures. A trifocal design divides light to support more than one focal range; a toric design aims to correct selected corneal astigmatism. One lens can combine both features.

Assessment and choice

Choice should follow eye examination and discussion of corneal shape, retinal and optic-nerve health, dry eye, pupil characteristics, prescription, visual priorities, occupation and night driving. A premium lens is not automatically the best choice for every eye.

Benefits and limitations

The goal may be to reduce dependence on spectacles at selected distances, but glasses can still be needed. Contrast, near vision and adaptation vary. Glare, halos and other light phenomena may be more noticeable with multifocal designs. Product-specific light-distribution or spectacle-independence percentages should not be applied without identifying the lens and study population.

Risks

Risks of lens surgery can include infection, inflammation, raised eye pressure, retinal problems, corneal swelling, incorrect lens power, lens-position problems, posterior capsule opacification, visual disturbance and, rarely, serious loss of vision. Further laser or surgical treatment may be required.

Follow-up

Recovery and return to driving or work vary. Patients should use prescribed drops, attend reviews and seek urgent clinical advice for severe pain, increasing redness or sudden loss of vision.
