Understanding the Most Common Types of Cataract Surgery:
Cataracts—a clouding of the eye’s natural lens—affect millions worldwide. Surgery is the only effective treatment, and over the decades, techniques have evolved significantly. This blog discusses cataracts and the most common types of cataract surgery commonly performed in clinical settings today.
What Is a Cataract?
A cataract is a clouding of the eye’s natural lens, which lies just behind the iris and pupil. In a healthy eye, the lens focuses light onto the retina to produce a clear image. But as we age—or due to factors like genetics, diabetes, smoking, or prolonged UV exposure—the proteins in the lens can begin to break down and clump together, forming cloudy areas. This cloudiness can cause blurry vision, difficulty seeing at night, glare from bright lights, and faded colors. Cataracts typically develop slowly and are a leading cause of vision loss in older adults. You can develop cataracts, or cloudy lens, in both eyes. Fortunately, cataract surgery removes the problem and is a highly effective and common procedure that can restore clear vision.
Common Types of Cataract Surgery: Natural Lens to Artificial Lens
1. Phacoemulsification (“Phaco”) Cataract Surgery
- What it is: The most widely used method in developed countries. A tiny incision is made in the cornea, and an ultrasonic probe breaks up the cataract into fragments, which are then suctioned out. A foldable intraocular artificial lens (IOL) is inserted in its place.
- Advantages:
- Minimally invasive (typically ≤3 mm incision)
- Often suture-free
- Faster recovery
- Lower induced astigmatism
- Surgery takes around 10–20 minutes
- Ideal for: Most typical cataracts, or cloudy natural lens —especially softer, less dense varieties.
2. Extracapsular Cataract Extraction (ECCE) & Manual Small Incision (MSICS) Cataract Surgery
- What it is: A larger incision (10–12 mm) allows removal of the cataract nucleus in one piece while leaving the lens capsule intact. MSICS is a variant that uses a self-sealing scleral tunnel, avoiding sutures.
- Advantages:
- Effective for very dense or mature cataracts too hard for phaco
- MSICS offers similar visual outcomes to phaco, with lower cost and comparable recovery
- Ideal for: Dense cataracts, especially in lower-resource settings or when phaco isn’t feasible.
3. Intracapsular Cataract Extraction (ICCE) Cataract Surgery
- What it is: An older technique involving removal of the entire lens—including its capsule—through a large incision, replaced with an artificial lens situated in front of the iris.
- Drawbacks:
- Very large incision (needs sutures)
- Higher risk of complications
- Rarely used today; typically reserved for unusual cases (e.g., capsule rupture, lens dislocation)
Newest Method: Femtosecond Laser‑Assisted Cataract Surgery (FLACS)
Another significant modern advancement is Laser‑Assisted Cataract Surgery (LACS), commonly referred to as FLACS:
- How it works: A femtosecond laser performs precision incisions on the cornea, opens the lens capsule, and may even begin lens fragmentation—all guided by computer imaging.
- Benefits:
- Enhanced precision in incisions and capsulotomy
- Reduces the energy required for the ultrasonic probe
- May offer advantages in complex or dense cataracts
- Discussion: While FLACS improves surgical accuracy, studies so far haven’t consistently shown superior visual outcomes or complication rates compared to standard phaco.
- Bottom line: It represents the newest method, but its clinical superiority depends on patient-specific factors and provider experience.
Are Premium Cataract Lenses Worth It?
Beyond standard cataract removal, patients choose from different intraocular lenses (IOLs). Options range from basic monofocals to advanced premium artificial lenses, including multifocals, trifocals, toric (astigmatism correcting), and accommodating IOLs.
Advantages of Premium IOLs
- Multifocal/trifocal IOLs: Provide clear vision at near, intermediate, and far distances—reducing dependency on glasses.
- Toric IOLs: Specifically designed to correct astigmatism.
- Accommodating IOLs: Mimic natural lens accommodation, offering a broader visual range.
Drawbacks & Considerations
- Cost: Medicare and many private insurers only cover basic monofocal IOLs; premiums bear extra cost.
- Side effects: Some patients report glare, halos, or reduced contrast sensitivity—though premium designs are improving.
- Value: For individuals seeking independence from glasses and who are good candidates, many providers believe premium options are worth the investment.
So, are they worth it?
- If you value lens-free vision across multiple distances and are comfortable covering the added cost, premium IOLs can be life-changing. However, if you’re fine with using glasses occasionally, a monofocal lens may suffice—and it’s fully covered.
Medicare Coverage: What’s Included?
Understanding insurance coverage is key. Here’s what Medicare provides for cataract surgery:
- Surgical Procedure & Basic IOL
- Medicare Part B covers the removal and implantation of a conventional (monofocal) IOL, either with traditional cataract surgery or laser-assisted methods. Discuss with your provider how to cover cataract surgery.
- You’ll pay 20% coinsurance after meeting the Part B deductible medicare.gov.
- Laser-Assisted Cataract Surgery
- Medicare can cover cataract surgery cost whether or not a laser is used—but does not pay the extra fee for FLACS.
- You’re responsible for laser upgrade fees.
- Premium IOLs
- These are not covered by Medicare. Any upgrade lenses are out-of-pocket expenses.
- Glasses or Contacts Post-Surgery
- After cataract surgery with an IOL, Medicare offers coverage for one pair of prescription glasses or contacts, usually within a set timeframe.
| Included by Medicare | Not Included by Medicare |
| Basic cataract surgery & monofocal IOL | FLACS upgrade fee |
| 20% coinsurance (after deductible) | Premium IOLs (multifocal, toric, accommodating) |
| One set of glasses/contact lenses | Additional post-operative enhancements |
Will Cataract Surgery Eliminate the Need for Glasses?
Cataract surgery often reduces—but doesn’t always eliminate—the need for glasses. After cataract surgery, your cloudy natural lens is replaced with a clear artificial intraocular lens (IOL), which improves vision significantly. If you receive a monofocal IOL, which is the type covered by Medicare, it’s typically set for either distance or near vision, meaning you may still need glasses for the opposite range (e.g., reading or driving). However, premium lenses—such as multifocal, trifocal, or toric IOLs—can reduce or even eliminate the need for glasses altogether by correcting for multiple distances and astigmatism. That said, even with premium options, some patients may still need glasses in low-light situations or for fine detail work. The decision depends on your specific visual goals and whether you’re willing to pay out-of-pocket for advanced lens technology.

Choosing the Best Cataract Surgery
Your vision is priceless. No one wants to have vision loss, cloudy vision, deal with eye drops or anything of that nature. The goal is to deal with the issue with little or no pain and move on with your daily life. Good news! That’s possible! Choosing the right cataract surgery doctor and lens setup isn’t just a medical choice—it’s a lifestyle decision. Whether you’re reading, driving, or enjoying hobbies, Midwest Eye Professionals can recommend cataract surgery with tailored options to meet both your visual and financial needs. Schedule an appointment to review your symptoms, give vision tests, perform a thorough eye exam and see if they suggest cataract surgery.
- Newest surgical method: Laser-assisted cataract surgery (FLACS).
