Over 28 million cataract removal surgeries happen yearly. The cases may triple by 2050. Asha, a 62-year-old teacher, struggled with blurry eyesight. Like 95% of cataract patients, she worried about which would be the best type of IOL for cataract surgery. Monofocal IOLs suit 85% of patients. But Asha wanted to read without glasses. So her doctor at the eye clinic suggested a multifocal IOL lens implant. Choosing the best IOL is life-changing—clear sight means better independence and confidence. According to WHO, cataracts remain the leading cause of blindness globally, affecting over 94 million people.
Would you choose sharper distance sight or freedom from glasses? We are here to help you select the best IOL for cataract surgery.
What Are Intraocular Lenses (IOLs)?
Intraocular lenses (IOLs) are artificial lens implants; these replace the natural eye lens after cataract removal. IOLs restore power-of-sight in 98% of cases. Advanced IOL lenses for cataract surgery, like multifocal and toric, improve near and distance sight. By 2030, the global IOL market is expected to exceed $6.5 billion. Better eyesight solutions and related innovations include light-adjustable and accommodating IOLs for better focus adjustments.
In India alone, around 6.5 million cataract surgeries are performed every year, making it one of the largest markets for IOLs in Asia.
Types of Cataract Lenses (IOLs):
Various IOL types cater to different ability-to-see needs, each with unique benefits and drawbacks. Each IOL has specific advantages. Choosing the types of lenses for cataract surgery will depend on your lifestyle, budget, and what kind of eyesight you need. Consulting the best ophthalmologist near you ensures the right decision during cataract removal. We are sharing all types of best IOL lenses for cataract surgery:
1. Monofocal IOLs:
These provide clear vision at a single fixed distance. Most patients opt for distant eyesight and use reading glasses. As per research, Monofocal IOLs have a 97% patient satisfaction rate due to their simplicity and clarity.
Pros:
- Affordable and widely available
- Sharp focus for one distance
- Minimal visual disturbances
Cons:
- Glasses needed for other distances
- No correction for astigmatism
2. Multifocal IOLs:
They have multiple focus points. In simple words this means that it will give you clear eye-sight at near, intermediate and far distances. Nearly 20% of patients now opt for multifocal lenses, especially in urban India, due to increasing demand for spectacle-free vision.
Pros:
- Reduces dependency on glasses
- Suitable for reading and driving
- Provides greater visual independence
Cons:
- Can cause glare, halos and reduced contrast
- Takes time for brain adaptation
3. Toric IOLs:
Designed for astigmatism correction, these IOL lenses improve clarity by adjusting for irregular corneal curvature. Astigmatism affects nearly 40% of cataract patients, making toric lenses essential for precise vision correction.
Pros:
- Sharp sight for astigmatic patients
- Reduces glass’s dependence on distance vision
- Available in monofocal and multifocal versions
Cons:
- Higher cost
- Requires precise alignment during surgery
4. Extended Depth of Focus (EDOF) IOLs:
These provide a continuous range of vision. It’s done by extending the focal range, thereby reducing reliance on multiple focus points. EDOF lenses are growing in popularity, with studies showing 88% of patients reporting satisfaction for intermediate vision tasks like computer work.
Pros:
- Fewer halos and glare than multifocal
- Good intermediate and distance sight
- Better contrast sensitivity than multifocal IOLs
Cons:
- Reading glasses needed for fine print
- Not ideal for those requiring strong near vision
5. Accommodating IOLs:
These lenses shift slightly inside the eye to mimic natural focusing. Thus these will be providing variable fields-of-vision post cataract removal. Accommodating IOLs are especially beneficial for people aged 45–65 who are still engaged in professional or active lifestyles.
Pros
- Improved intermediate and distance vision
- Reduced dependency on glasses
- More natural power-to-eyes compared to multifocal
Cons
- Near vision not as strong as multifocal IOLs
- Lens movement may decrease over time
6. Light Adjustable Lenses (LALs):
These IOLs are customized post-surgery using UV light. They then allow fine adjustments for optimal vision by becoming UV protection lenses. A clinical trial showed that over 92% of patients using LALs achieved 20/20 vision after final light adjustments.
Pros
- Tailored power-of-eyes correction after implantation
- Reduces prescription errors
- Minimizes post-surgical surprises
Cons
- Requires multiple light treatments
- More expensive than traditional IOLs

Comparison Table:
| IOL Type | Vision Range | Glasses Dependency | Ideal For | Cons / Risks |
| Monofocal | Single distance (usually far) | High (for reading) | Budget-conscious, basic clarity | No astigmatism correction |
| Multifocal | Near + Intermediate + Far | Low | Reading + driving | Halos, glare, takes time to adapt |
| Toric | Corrects astigmatism | Low (for distance) | Astigmatic patients | Requires precise alignment |
| EDOF | Intermediate + Distance | Medium (for near tasks) | Daily tasks, working adults | Not strong for near vision |
| Accommodating | Intermediate + Distance | Low | More natural eye movement | May weaken over time |
| Light Adjustable Lens (LAL) | Customized vision | Very low | Precise post-op correction | Expensive, needs UV light sessions |
Factors to Consider When Choosing an IOL:
Choosing the best IOL for cataract surgery depends on your individual eye-sight needs, your own lifestyle, and of course your eye health. Improper selection can cause refractive errors in 2-5% of cases.
- Monofocal IOLs suit 85% of cataract patients, offering clear distance sight.
- Multifocal IOLs, chosen by 20%, reduce glasses dependency.
- Toric IOLs correct astigmatism in 37% of cases.
- In 2023, it was reported that 3 out of 10 patients now actively inquire about premium lenses before surgery.
More than 50% of people over 60 also suffer from presbyopia, increasing the need for multifocal or EDOF lenses. - Age matters—presbyopia affects 1.8 billion people globally. Thus, eye surgeons will examine the pupil size, corneal shape, and retinal health to select the correct types of IOL for cataract surgery. While Contact Lens options have long helped manage vision issues temporarily, IOLs offer a permanent solution post-cataract surgery.
- Costs vary for different types of lenses for cataract surgery; premium IOLs cost 3-5 times more than standard ones.
Additional Aspects to Look for:
- Silicone or acrylic IOLs impact durability and biocompatibility.
- Some IOLs reduce macular degeneration risk, benefiting 196 million AMD patients worldwide.
- Certain IOLs work better with laser-assisted surgery, which improves precision in 35% of procedures.
- Night vision consideration because multifocal IOLs may cause halos/glare, affecting 18% of users.
Some newer IOLs now include blue light filters, protecting users from digital strain, which is reported by 58% of adults in India.
Which IOL Lens is the Best?
Which IOL is best? The answer is – what your doctor suggests for your eyes, that shall be the best IOL for cataract surgery. For example, consider two friends, Raj and Aman.
Raj loves reading, while Aman enjoys driving. Raj chooses a multifocal IOL for both near and far vision. Aman picked a toric IOL to fix his astigmatism. Their doctor explains no single “best” IOL exists—only the best fit for each lifestyle.
Studies show 85% of patients pick monofocal IOLs for clarity. On the other hand, premium IOLs reduce glasses dependency by 80%. The right choice depends on personal needs, your eye health and the intensity of clear eyesight choices you have.
What are the Issues and Complications Related to IOL implantation:
- Dry eye symptoms worsen post-surgery in nearly 42% of cases.
- Glare and halos impact 25% of multifocal IOL users, especially at night.
- IOL lens dislocation occurs in rare 1-3% of cases, leading to visual disturbances.
- Posterior capsule opacification (PCO) affects up to 30% of patients. It occurs when the thin membrane (capsule) behind the new artificial lens becomes cloudy, causing blurry eyes.
- Endophthalmitis, a rare but severe infection, occurs in 0.1% of surgeries.
- Residual refractive errors require corrective glasses in 15-20% of patients.
- To avoid complications, over 78% of surgeons now recommend pre-surgical ocular surface evaluation and biometry scans.
For managing such complications, especially dryness or irritation, your nearby pharmacy can provide over-the-counter lubricating drops, sterile eye pads, and guidance on post-operative care essentials.
Is Cataract Surgery Performed Differently Depending on the Type of Lens You Choose?
Dr. Meera, an eye surgeon, explains: “Patients often ask us which IOL lens is best. Will surgery also vary? In Feb 2025, we had two IOL lens Implantation cases from the same family. Grandpa Ravi needed cataract surgery. We explained to them that standard mono-focal lenses require simple surgery – 10–15 minutes time per eye. But Ravi wanted a multifocal IOL lens for cataract surgery typically for both near and far eye-sight, thus needing a specific alignment. His daughter Meera had astigmatism. Thus, her toric IOL required extra corneal markings. Advanced lenses like light-adjustable IOLs involved post-surgery UV adjustments. Though the basic procedure stays the same, lens choice affects precision, technique, and aftercare steps also.”
Laser-assisted cataract surgeries are now used in 35–40% of urban hospitals in India for premium lens implantation.
