While recent launches with expanded parameters and improved materials and lens wettability may help reduce industry-wide contact lens dropout, there are still unmet needs in the toric space, namely the multifocal market. A daily disposable toric multifocal design is much needed. Fitting with the Golden Rule will likely help you build patient loyalty and referrals.
Provide the highest standard of care and potentially prevent dropouts by not missing opportunities to treat the ocular surface and refit patients into toric lenses to ensure happy patient and practice outcomes.

Loading, please wait Like toric soft contact lenses for astigmatism , toric IOLs have different powers in different meridians of the lens to correct the asymmetric power of the eye that is characteristic of astigmatism.
Cataract surgery with a toric lens implant IOL is essentially the same as cataract surgery with a conventional IOL, but with a couple of important differences. Prior to surgery, measurements are taken to enable cataract surgeons to choose the most beneficial toric IOL power and the required orientation of the implant in the eye to correct the astigmatism successfully.
Toric IOLs have special markers on the peripheral parts of the lens that enable the surgeon to see the orientation of the astigmatism correction in the lens. Once the toric IOL is implanted in the eye, the surgeon then rotates the lens so the astigmatism correction is properly aligned for best results.
Use of a toric IOL during cataract surgery does not increase the risk of common cataract surgery complications , but a misaligned toric IOL can cause blurred vision that cannot easily be corrected with eyeglasses or contact lenses. Research has shown that toric lenses produce excellent visual results after cataract surgery and can correct astigmatism more effectively than limbal relaxing incisions. One study found that 94 percent of astigmatic eyes treated with toric lens implants had 0.
And studies evaluating patient satisfaction after cataract surgery have found the majority of patients receiving toric IOLs are highly satisfied with their vision after surgery. One study found 92 percent of patients report no difficulty with driving at night without eyeglasses six months after surgery, and 97 percent of patients receiving toric lens implants would choose the same IOL to be implanted again. One reason that more people aren't opting for toric lens implants to reduce astigmatism after cataract surgery is the added cost of toric IOLs.
Though cataract surgery usually is fully covered by Medicare and all other medical insurance plans, the added costs associated with premium lens implants such as toric IOLs are an out-of-pocket expense that is the patient's responsibility. Another factor of why the use of toric IOLs is not as prevalent as it could be is that properly implanting a toric IOL is more challenging for cataract surgeons than using a conventional spherical IOL that's not designed for astigmatism correction surgery.
To correct astigmatism effectively, a toric IOL has to be positioned precisely within the eye, with the astigmatism correction aligned perfectly with the astigmatism present in the eye. Also, the toric IOL must be securely positioned so it does not rotate after it is implanted.
