What Is a Cataract?

A cataract is a clouding of the eye’s natural lens, which sits behind the iris and pupil. The lens is normally transparent, allowing light to pass through and focus on the retina at the back of the eye. When a cataract develops, the lens becomes increasingly opaque, scattering light and reducing the quality of your vision.

According to the National Eye Institute, cataracts are one of the Trusetd Source Checkbox Trusted Source Cataract Data and Statistics National Eye Institute Go to Source leading causes of vision loss worldwide, particularly in older adults. The condition develops gradually in most cases, and many people don’t realize they have cataracts until they notice changes in their vision during routine eye exams or daily activities.

Cataracts are not a film that grows over the eye, nor are they contagious. Instead, the proteins within the lens clump together over time, creating the clouding effect. This process is typically painless, which is why regular eye exams are essential for early detection.

What Causes Cataracts?

Cataracts develop for several reasons, and understanding the risk factors can help you take preventive steps:

Age-Related Cataracts

The most common type, age-related cataracts, develop as the proteins in the lens naturally break down over time. This is a normal part of aging, and most people over 60 experience some degree of cataract formation.

UV Exposure

Prolonged exposure to ultraviolet (UV) radiation from the sun can accelerate cataract development. Wearing UV-protective sunglasses and hats when outdoors can help reduce this risk.

Medical Conditions

Diabetes, high blood pressure, and other systemic diseases can increase your risk of developing cataracts earlier than average.

Medications

Certain medications, particularly corticosteroids used to treat inflammation or autoimmune conditions, may increase cataract risk with long-term use.

Eye Injury or Trauma

Traumatic cataracts can develop after an eye injury, sometimes immediately or years later.

Genetics

If cataracts run in your family, you may be at higher risk of developing them yourself.

Types of Cataracts

Understanding the different types of cataracts can help you recognize symptoms early:

Nuclear Cataracts

These develop in the center (nucleus) of the lens and are the most common age-related type. They often cause a gradual hardening of the lens and may initially improve near vision before worsening overall quality.

Cortical Cataracts

These form in the cortex, the outer layer of the lens, and typically develop as white opacities that radiate from the center like spokes on a wheel. They often cause glare and difficulty with contrast sensitivity.

Posterior Subcapsular Cataracts

These develop at the back of the lens and can significantly impact reading and night driving, even when the cataract is small. They tend to progress more rapidly than other types.

Congenital Cataracts

Present at birth or developing in early childhood, congenital cataracts may be inherited or result from maternal infections during Trusetd Source Checkbox Trusted Source Types of Cataracts National Eye Institute Go to Source pregnancy.

Cataract Symptoms and When to Seek Help

Cataracts develop slowly, and early symptoms may be subtle. Common signs include:

  • Cloudy, blurry, or dim vision
  • Difficulty seeing at night or in low-light conditions
  • Increased sensitivity to light and glare
  • Halos around lights
  • Double vision in one eye
  • Fading or yellowing of colors
  • Frequent changes in eyeglass or contact lens prescription
  • Difficulty reading or performing detailed Trusetd Source Checkbox Trusted Source Cataracts (Age-Related) Cleveland Clinic Go to Source tasks

If you’re experiencing any of these symptoms, schedule a comprehensive eye exam with Kovach Eye Institute. Early detection allows us to monitor your cataracts and determine the best time for surgery.

When Is It Time for Cataract Surgery?

Cataract surgery is recommended when the clouding begins to interfere with your daily activities and quality of life. There’s no need to wait until a cataract is “ripe” or fully developed, as modern surgical techniques allow for safe removal at any stage.

Your ophthalmologist will help you decide if surgery is right for you based on:

  • How much the cataract affects your vision
  • Your visual needs and lifestyle
  • Your overall eye health
  • Your ability to tolerate the procedure and recovery

Some patients choose surgery earlier if their profession or hobbies require excellent vision. Others may wait longer if their cataracts don’t significantly impact their daily life. The decision is entirely yours, made in consultation with your eye care team.

Intraocular Lens (IOL) Options

One of the most important decisions in cataract surgery is selecting the right intraocular lens (IOL) to replace your eye’s natural lens. There are two main categories of IOLs: standard (monofocal) IOLs and Advanced Technology IOLs. Advanced Technology IOLs—also known as lifestyle or premium lenses—are designed to provide more comprehensive vision correction and may reduce your dependence on glasses or contact lenses.

Monofocal IOLs

A monofocal IOL is a standard lens that corrects vision at a single distance, most commonly distance vision. Patients who choose a monofocal IOL will typically still need glasses for near or intermediate vision tasks. Standard monofocal IOLs are generally covered by insurance.

Multifocal and Trifocal IOLs

Multifocal and trifocal IOLs are advanced technology lenses designed to correct vision at multiple distances, including near, intermediate, and distance. These lenses use a specialized optical design to improve range of vision. Some patients may notice visual phenomena such as glare or halos, particularly at night, which often improve with time.

Astigmatism-Correcting IOLs

Astigmatism-correcting IOLs, also known as toric lenses, are designed to address astigmatism in addition to correcting vision. There are both monofocal toric lenses (for single-distance correction) and advanced toric lenses that can correct vision at multiple distances while also treating astigmatism.

Extended Depth of Focus (EDOF) IOLs

Extended Depth of Focus (EDOF) IOLs are advanced technology lenses that create a continuous range of vision by elongating the eye’s focal point. This allows for improved distance and intermediate vision, with functional near vision in many cases, often with fewer visual side effects compared to some multifocal lenses.

Light Adjustable Lenses™ (LAL)

The Light Adjustable Lens (LAL) by RxSight is an advanced technology intraocular lens made from a specialized photosensitive material that allows vision to be customized after cataract surgery. Once your eye has healed, your doctor can precisely adjust the lens using UV light treatments performed in the office. This process allows for refinement of your vision based on your real-world results, offering a level of customization not available with traditional IOLs. Multiple adjustments may be performed before the final prescription is locked in.

During your consultation at Kovach Eye Institute, your surgeon will evaluate your eyes, discuss your vision goals, and recommend the IOL that best aligns with your lifestyle and visual needs.

Advanced Cataract Surgery Technology

At Kovach Eye Institute, we combine surgical expertise with advanced technology to deliver highly precise, customized cataract surgery for patients throughout the Chicagoland area.

Femtosecond Laser Cataract Surgery with CATALYS®*

While traditional cataract surgery uses handheld instruments and ultrasound (phacoemulsification), select patients may benefit from a laser-assisted bladeless approach that enhances accuracy during the procedure. 

We utilize the CATALYS® Laser System, from Johnson & Johnson – an advanced femtosecond laser platform featuring high-resolution 3D imaging and computer-guided precision to support meticulous surgical planning and execution. 

The CATALYS® system allows surgeons to: 

  • Create precise corneal incisions
  • Perform a highly accurate capsulotomy 
  • Gentle softening of the cataract before removal
  • Customize treatment using real-time imaging
  • Ability to treat certain types of astigmatism
  • Designed to support a comfortable surgical experience and recovery

By increasing precision during these critical steps, laser-assisted cataract surgery can enhance surgical consistency. Studies have shown that patients undergoing femtosecond laser–assisted cataract surgery may have up to a Trusetd Source Checkbox Trusted Source Study: Effective lens position advances accuracy Krader CG Go to Source 20% higher likelihood of achieving 20/20 vision or better compared to surgery performed with a manual blade, depending on individual factors and lens selection.

During your cataract consultation, our surgeons will determine whether laser cataract surgery is the best option for your eyes and vision goals.

*Disclaimer: Bladeless cataract surgery, also known as laser-assisted cataract surgery, uses advanced laser technology to assist with certain steps of the procedure. However, it may not be appropriate for every patient or for every part of the surgery. Your surgeon will determine the safest and most effective surgical approach based on your eye health and individual needs. In some cases, surgeons may use traditional microsurgical instruments or a combination of laser technology and manual techniques to achieve the best possible outcome.

ORA with VerifEye™ Intraoperative Aberrometry

Selecting the correct intraocular lens (IOL) power is critical to achieving optimal results. Kovach Eye Institute uses ORA with VerifEye™, a real-time intraoperative measurement system that helps refine lens selection during surgery.

After the cataract is removed, ORA:

  • Measures the eye’s refractive power
  • Confirms ideal IOL strength
  • Assists in astigmatism correction
  • Supports precision placement of advanced technology lenses

Because these measurements are taken during surgery — not just before — ORA adds an additional layer of accuracy, particularly for patients choosing toric, multifocal, extended depth of focus, or Light Adjustable Lenses.

The Cataract Surgery Procedure

Cataract surgery is one of the most commonly performed surgical procedures in the United States, with a high success rate. Here’s what to expect:

Pre-Operative Evaluation

Before surgery, you’ll undergo comprehensive testing to measure your eye’s dimensions, corneal curvature, and lens power. These measurements ensure precise IOL selection and optimal visual outcomes. You may be asked to discontinue certain medications, particularly blood thinners, in the days before surgery.

The Surgery

Cataract surgery typically takes 15-20 minutes per eye.  You’ll receive numbing drops and mild sedation to keep you comfortable. Your surgeon will make a small incision in the cornea and use phacoemulsification, a technique that uses ultrasonic vibrations to break up the cloudy lens into tiny fragments. These fragments are then gently suctioned out, and the IOL is inserted through the same small incision. In many cases, the incision is so small it doesn’t require stitches.

While the procedure itself is brief, patients should plan to spend approximately 3-4 hours  at the surgery center and set aside the full day, as timing can vary based on preparation and recovery.

Recovery Room

After surgery, you’ll spend time in the recovery area while the numbing drops wear off. You’ll receive post-operative instructions and eye drops to prevent infection and reduce inflammation.

 

Recovery and Post-Operative Care

Immediate Recovery (First 24 Hours)

Most patients notice improved vision within hours of surgery, though vision may be slightly blurry initially. You’ll need someone to drive you home, as you cannot drive on the day of surgery.

First Week

During the first week, follow these guidelines:

  • Use prescribed eye drops as directed, typically four times daily
  • Avoid rubbing or pressing on your eye
  • Wear the protective shield provided, especially at night
  • Avoid strenuous activity, heavy lifting, and swimming
  • Wear sunglasses to protect your eye from bright light

Weeks 2-4

Vision continues to improve as the eye heals. You can gradually resume normal activities, though you should still avoid heavy exercise and contact sports. Most patients can return to work within a few days to a week, depending on their job.

Full Recovery

Most patients achieve stable vision within 4-6 weeks after cataract surgery. Your final eyeglass prescription can be determined at your post-operative visit, typically 4-6 weeks after surgery.

Potential Complications and How We Manage Them

While cataract surgery is very safe, like any surgical procedure, there are potential risks. Your surgeon will discuss these with you during your consultation:

Posterior Capsule Opacification (PCO)

The most common complication, occurring in approximately 20-30% of patients within 5 years after surgery, PCO develops when the back of the lens capsule becomes cloudy. This is easily treated with a quick laser procedure called YAG capsulotomy, which restores improved vision.

Infection

Post-operative infection is rare, occurring in less than 1% of cases. Proper use of prescribed antibiotics and eye drops significantly reduces this risk.

Inflammation

Some inflammation is normal after surgery and is managed with prescribed anti-inflammatory eye drops.

Swelling (Corneal Edema)

Temporary swelling of the cornea may occur but typically resolves within days to weeks with appropriate eye drops.

Retinal Detachment

This rare complication occurs in less than 1% of cataract surgeries. Symptoms include sudden flashes of light, floaters, or a shadow in your peripheral vision. Contact us immediately if you experience these symptoms.

Our surgeons’ extensive experience and advanced surgical techniques minimize the risk of complications. Should any occur, our team is prepared to manage them promptly and effectively.

Cost and Insurance Coverage

In many cases, cataract surgery is covered by Medicare and most private insurance plans when it is considered medically necessary.

What Insurance Typically Covers:

  • Basic cataract surgery with a standard monofocal Intraocular Lens (IOL)
  • Surgeon fees and facility costs
  • Pre-operative and post-operative care
  • Anesthesia fees

*Copays, deductibles, and coinsurance may apply

Out-of-Pocket Costs:

Patients who choose advanced technology intraocular lenses (including toric, multifocal, or light adjustable lenses) or astigmatism correction using  laser-assisted cataract surgery, will have additional out-of-pocket costs since these upgrades are not typically covered by insurance.

Because every patient’s eyes and vision goals are unique, the best way to understand your exact cost is through a personalized consultation. During your visit, our team will review your insurance benefits, discuss advanced technology lens options and premium services, and provide a detailed cost estimate.

We accept most major insurance plans and offer financing  options for patients without insurance or those choosing advanced technology lens upgrades.

Cataract surgery typically takes 15-20 minutes per eye. While the procedure itself is brief, patients should plan to spend approximately 3-4 hours at the surgery center and set aside the full day, as timing can vary based on preparation and recovery.

This depends on the IOL you choose and your eye’s natural focusing ability. With a monofocal IOL, you’ll likely need glasses for reading or near vision. Multifocal or EDOF lenses may reduce or eliminate your need for glasses, though some patients still prefer them for certain tasks. Your doctor will discuss your options during your consultation.

Most patients can return to light activities within a few days and resume normal activities within 1-2 weeks. Strenuous exercise and contact sports should be avoided for at least 2-4 weeks. Your surgeon will provide specific guidelines based on your individual healing.

No. Your eye will be numbed with drops, and you’ll receive mild sedation to keep you comfortable. You may feel slight pressure during the procedure, but you should not experience pain. If you do, let your surgeon know immediately.

Typically, surgery is performed on one eye first, allowing it to heal before operating on the second eye. This is usually done 1-2 weeks later, giving you time to adjust to the new IOL in the first eye.

If you’re experiencing cloudy or blurry vision, difficulty seeing at night, increased glare sensitivity, halos around lights, or fading colors, these may be signs of cataracts. Schedule a comprehensive eye exam to determine if cataract surgery is right for you.

Most patients notice improved vision within hours of surgery. Functional vision typically returns within a few days, and stable vision is achieved within 4-6 weeks. You’ll have post-operative visits to monitor your healing and ensure optimal results.

In the early stages of cataract development, vision changes may be managed with updated eyeglass prescriptions, brighter lighting, or anti-glare sunglasses. However, these are temporary solutions, and surgery is the only way to permanently remove a cataract. Your surgeon will discuss all options during your consultation.
