What are the disadvantages of multifocal lenses?
Cons of multifocal IOLs
- Difficulty seeing at a close distance: While this is rare, sometimes, patients may require reading glasses. This depends on their existing prescription and eye health before surgery.
- Night vision, halos, or glares: Only about 1% of our patients develop halos and glares on lights after dark.
Who should not get multifocal IOL?
If someone has an ocular comorbidity in either eye (eg, severe dry eye disease, irregular astigmatism, epiretinal membranes, macular degeneration), he or she is not eligible for a multifocal IOL. In my practice, this means that 50% of patients are ineligible.
What are the side effects of IOL?
Risks
- You may lose vision.
- You may develop debilitating visual symptoms.
- You may need additional eye surgery to reposition, replace or remove the phakic lens implant.
- You may be under treated or over treated.
- You may develop increased intraocular pressure.
- Your cornea may become cloudy.
- You may develop a cataract.
How successful are multifocal IOLs?
Compared to monofocal IOLs, multifocal IOLs had statistically significantly better pooled results for the outcome of near vision (10 studies, 1025 patients, mean difference in logMAR of -0.26 (95% CI -0.37, -0.15)); spectacle dependence (12 studies, 1237 patients, relative risk of 0.27 (95% CI 0.20, 0.38)) and …
Can a multifocal lens be removed?
For example, if a multifocal IOL is implanted to correct presbyopia and it doesn’t provide adequate near vision or it causes halos or other vision problems, it can be removed and replaced with a different presbyopia-correcting IOL or a conventional single vision IOL.
How long do multifocal lenses last?
Multifocal lens cataract surgery
Unlike multifocal contact lenses, they don’t need regular care or replacement, they last forever! Many patients who have multifocal IOLs find that they don’t need to wear glasses after cataract surgery, or if they do, they may only need reading glasses for fine print.
Is IOL surgery safe?
It has been reported by ophthalmologists that the modern cataract-intraocular lens (IOL) surgery is safe and complication-free most of the time. This makes the watchword for any cataract surgeon to be ‘implantation,’ ‘implantation,’ ‘implantation.
Why is my eyesight worse after cataract surgery?
It is very common to have blurry or unclear vision in the days and sometimes even weeks after cataract removal. Most of the time, this is caused by normal swelling in the eye which occurs as a part of surgery. Patients with larger, denser and/or firmer cataracts are more likely to experience more inflammation.
How long do multifocal implants last?
Once healed, which takes 1 or 2 days, this capsule holds the IOL securely for long-term visual acuity. The material from which the IOL is made is crystal clear and does not break down over time the way the natural lens of the eye does. This means that this new lens could last indefinitely, never requiring replacement.
Which multifocal IOL is best?
Although there have been previous version of the AcrySof® IQ ReSTOR® IOL the +3.0 D add power is the best choice for true performance at all distances. It provides improved intermediate vision over the original AcrySof® IQ ReSTOR® IOL +4.0 D, with similar near and distance visual acuity.
How long do multifocal IOLs last?
Can an IOL be removed and replaced?
Although it is rarely necessary, the IOL can be removed and replaced. Although the need to remove the lens is very unusual, the most common reason would be that the power is incorrect, despite all of the preliminary calculations. Another reason would be if the IOL shifted out of position inside the eye.
What is the most common complication after cataract surgery?
Cystoid Macular Edema
CME is the most frequent complication after an uncomplicated cataract surgery.
Why is my eyesight getting worse after cataract surgery?
How successful is IOL surgery?
Smaller incisions and the need to reduce trauma require new micro-instrumentation for best outcomes. Intraocular lens (IOL) implantation is a well-established procedure with a success rate of 95% to 98%.
Is it risky to replace an IOL?
Any additional surgical procedure such as an IOL exchange has higher risks than the original surgery: additional incisions in the eye which can affect astigmatism and healing, further potential for corneal endothelial cell loss, and a repeat exposure to the risks of endophthalmitis and retinal complications.
Who is not suitable for lens replacement?
If you have another eye condition, such as macular degeneration, you may not benefit from a lens replacement procedure.
Can the IOL be removed and replaced?
So, can the intraocular lens be removed and replaced? Our answer is yes. If there is an issue with your IOL, it can be replaced with another one. This usually occurs when the lens does not provide adequate vision correction or causes problems like double vision.
At what age is lens replacement recommended?
If you are over 45 years old, lens replacement should be an option you consider. Lens replacement provides the dual solution of distance and near vision in both eyes, unlike blended vision which treats one eye for distance and one eye for near.
How long do IOL lenses last?
Patients often ask “how long will the implant last, doctor?” The response is usually, “we expect it to last your lifetime, we are so confident in this that we even implant them in children”.
Can you fly after lens replacement?
Normal cataract surgery would not pose any problems for air travel, even right away. Once your doctor has cleared you for normal activities, flying is fine. Just don’t miss your follow-up appointments.
Which lens is better monofocal or multifocal?
Multifocal intraocular
Monofocal IOLs provide the clearest vision at one distance. Multifocal intraocular lenses, meanwhile, are used to simultaneously improve near vision, intermediate vision, and distance vision.
When can I do housework after cataract surgery?
Additionally, try not to do any housework or cooking after cataract surgery for the first two weeks. If you cannot avoid this, wear your eye shield to reduce the risk of irritation and infection.
What activities should be avoided after cataract surgery?

- Performing Strenuous Activities.

- Rubbing Your Eye.
How long does it take to adjust to multifocal IOL?
•
It may take them three days, three months or six months to adjust and learn how to adapt to their new vision. Some patients may not ever adapt and, for them, we should be ready to exchange a multifocal or EDOF lens for a monofocal IOL.
