Cataract Surgery Implanting Multifocal Lens

Multifocal IOL is a type of prosthetic lens used in cataract surgery. There are Some patients choose to have this lens replaced before they have developed cataracts a procedure which is known as a refractive lens exchange. Rotary Eye Helps with cataract or lens replacement surgery the patient has natural lenses which are replaced with multifocal IOLs.

The percentage of patients who achieved uncorrected distance visual acuity of 20/40 or better at 6 months was 92% in the multifocal group and 97% in the monofocal group. A cataract is a vision-hampering disease result is from the gradual cloudiness and the thickening of the natural lens of the eye.  It is the leading cause of reversible blindness in the whole world. It is definitive treatment is lens extraction and replacement of an intraocular lens implant. Different methods are utilized to extract the intraocular lens e.g., intracapsular extraction, extracapsular extraction, or phacoemulsification the latter of which is most commonly used. The replacement of multifocal intraocular lenses during cataract surgery allows patients to gain distance and near vision but careful selection of patients is critical and it depends on multiple factors. But the thing is that not all patients are candidates for multifocal lenses. Multifocal IOL is a type of prosthetic lens used in cataract surgery. There are Some patients choose to have this lens replaced before they have developed cataracts a procedure which is known as a refractive lens exchange.

Multifocal Lenses Implant:

• Traditional mono-focal lenses give the patients either good distance or good near vision but not both are given. These lenses are implants that are a manifestation of modern technology to meet the expectations of different patients and improve both distance and near vision. They divide light into different focal points and provide better visual quality. However, the careful selection of the patient and type of lenses are too critical to the success of multifocal lens implants. Multifocal lenses may use for refraction of light, diffraction, or both to help to focus objects on the retina.

Refractive IOLs

• Refractive lens implants create multifocal focal points and usually provide far and intermediate vision. However, they have limited near vision.
• They depend on the dynamics/size of pupils.
• Refractive lenses may cause halos and glare.
• Sometimes, they are designed with a changing curvature to provide vision across all distances.

Diffractive IOLs

• They are formed by diffractive microstructures in concentric zones.
• Generally, they provide good far and near vision.
• Intermediate vision may be limited.
• They also depend on pupil dynamics/size.
• Lower incidence of glare and halos than refractive IOLs.

Trifocal IOLs

• Provide distance, near and intermediate vision.
• They may cause glare and halos.

Multifocal IOL offers many benefits for patients who are interested in removing their need to wear or becoming less dependent on glasses. Because of their bifocal structure, these two-in-one lenses are not dependent upon eye movement and alter themselves independently to optimize incoming light. Multifocal IOLs can also be combined with their single-lens or sister IOLs for optimal vision enhancements. Multifocal IOLs are also safe and comfortable and they act much like permanent contact lenses and can be implanted in either one or both eyes. It is completely normal to experience a little-blurred vision your eyesight settlement for a day or two or in some cases for a week or two. Some people can be required glasses for distance or near vision after cataract surgery but they also have the option of laser eye surgery to decrease the need for glasses.

The majority of patients who are received either accommodating or multifocal IOLs will remain satisfied with their lens of choice more than 5 years after the original surgery. Glare and halos remain more noticeable in patients who are received multifocal lenses. Your optician or eye doctor might prescribe multifocal lenses if you have any trouble seeing both near and far away objects. They may be recommended for individuals who are experiencing eye strain or fatigue and headaches when they are reading or writing.

When do people need a lens implant?

• At the time of cataract surgery, there is a cloudy lens which is also known as a cataract is removed and a clear new plastic lens is put in place of the old cloudy lens. If you have to need a lens implant due to cataract surgery or age-related vision deterioration your options will be a mono-focal lens or multifocal lens.

When is a mono-focal lens best?

• The new plastic lens used in cataract surgery is called a lens implant and is usually a mono-focal lens.  Monofocal means that the lens only focuses on one distance from the current place. A mono-focal lens is used to make the vision good for seeing at a distance from your current place. The person receiving the lens will need reading glasses for close work for better results. Monofocal lenses give the best quality of vision as they only have one ‘job’ to do and that is to give good distance visions. Some people want to be free of glasses or both for distance and for reading.
• Although it can take up to four to eight weeks to fully recover from cataract surgery, most people will notice their vision begin to improve much sooner, and typically there should be little pain or discomfort during this period. Rotary Eye has some follow-up on appointments with your provider during this time. While each person heals differently, many patients report drastically better vision within the first 24 hours of the procedure. Plan on taking one to three days off of work to be sure you have enough time to rest, but it is normal to resume most normal activities within a couple of days.
