What happens if a toric lens rotates out of alignment after surgery?
A small percentage of toric IOLs shift rotationally during early healing, which can reduce the quality of astigmatism correction. If this occurs, our surgeons can perform a minor repositioning procedure to realign the lens and restore optimal vision.
Can toric lenses also correct nearsightedness or farsightedness?
Yes, toric IOLs are available in a range of base powers that correct nearsightedness or farsightedness in addition to astigmatism. The appropriate prescription is determined through precise pre-operative measurements taken by our team.
Is a toric lens the only way to correct astigmatism during cataract surgery?
Toric IOLs are the most effective method for correcting moderate to high astigmatism at the time of cataract surgery, but limbal relaxing incisions (LRIs) are an alternative for lower degrees of astigmatism. Our surgeons will recommend the most appropriate technique based on your individual measurements and prescription.
Can I have a toric lens if I've had LASIK previously?
Patients with prior LASIK or PRK can still receive toric IOLs, though pre-surgical measurements require additional calculations to account for the previously altered corneal shape. Our surgeons’ combined expertise in refractive surgery and lens implantation makes her especially qualified to manage this patient population.
How is the correct toric lens power determined before surgery?
Pre-operative corneal topography and biometry measurements are used to precisely map the degree and axis of astigmatism, which then guides lens selection and alignment planning. At Pacific Vision Institute, advanced diagnostic imaging ensures that these calculations are as accurate as possible before any surgical decisions are made.
Do toric lenses look or feel different inside the eye compared to standard IOLs?
Toric lenses feel no different from standard monofocal IOLs once implanted; patients do not experience any sensation from the lens itself. The difference lies entirely in the optical design, which is invisible to the patient but highly meaningful for visual clarity.
Will my astigmatism correction with a toric lens remain stable long-term?
Toric IOLs are designed to provide stable, long-term astigmatism correction as a permanent implant. Significant rotation or change in effectiveness after full healing is uncommon, and the vast majority of patients maintain their corrected vision for life.
Can toric lenses be combined with multifocal optics?
Yes, multifocal toric IOLs are available and can address astigmatism while also providing multiple focal points for near, intermediate, and distance vision. Our surgeons will evaluate whether you are a strong candidate for this combination lens during your pre-operative consultation.
