What is a multifocal toric lens?
Multifocal and toric lenses that are implanted during surgery allow patients to be more independent from the use of glasses by correcting conditions of astigmatism or near and far sighted vision.
What is toric IOL?
Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of 1 D or more in cases undergoing cataract surgery. Comprehensive literature search was performed in MEDLINE using “toric intraocular lenses,” “astigmatism,” and “cataract surgery” as keywords.
What is multifocal IOL surgery?
Multifocal IOLs are a type of prosthetic lens used in cataract surgery. Some patients choose to have this lens placed before they have developed cataracts, a procedure known as a refractive lens exchange. During cataract or lens replacement surgery, the patient’s natural lenses are replaced with multifocal IOLs.
What is the difference between toric and multifocal lenses?
Unlike standard or “monofocal” implant lenses which provide either distance or near vision, but not both, multifocal lenses allow you to see clearly at near, middle, and far distances. Toric lenses correct astigmatism, which is due to an uneven curve in your cornea or lens, or an abnormal shape of the eyeball itself.
What’s the difference between toric and multifocal?
A toric IOL can correct up to 4.50 diopters of corneal astigmatism. Multifocal IOLs correct a range of visual fields. The newest designs split light into several focal points to provide high quality vision.
Are toric IOL lenses worth it?
Excellent Toric IOL Outcomes
Research has shown that toric lenses produce excellent visual results after cataract surgery and can correct astigmatism more effectively than limbal relaxing incisions.
What is the success rate of toric IOL?
Toric lenses are highly successful in 95 percent of patients, allowing them to see objects clearly at a distance without relying on any other form of corrective lens.
Why are toric lenses so expensive?
It generally takes more expertise for an eye doctor to fit a patient for toric contacts than it does for regular lenses. For this reason, a toric lens fitting may cost more than a regular contact lens fitting. Since torics are more complex in design, the cost of replacing them will be higher than most regular contacts.
Which is better monofocal or multifocal?
Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs.
Should astigmatism be corrected during cataract surgery?
Astigmatism can affect your near and distance vision, often causing mild blurring or double vision. We are able to determine the amount of astigmatism affecting your vision during your cataract evaluation. The good news is, if you have astigmatism, it can now be corrected during your advanced laser cataract procedure.
