An intraocular lens


An IOL (intraocular lens) is inserted during cataract surgery to replace your eye's clouded natural lens. IOLs can help you see clearly.

The board-certified ophthalmologists at Deen-Gross Eye Centers can provide the right IOL for your unique goals and lifestyle.

Why is having state-of-the-art IOLs surgically placed by our skilled Merrillville, IN, area ophthalmological surgeons the clear choice?

A grandchild's first smile. A spectacular Indiana sunset. Blurry vision can take you out of the moment and make these precious events difficult to enjoy. The board-certified ophthalmologists at Deen-Gross Eye Centers in Merrillville and Hobart can perform cataract surgery and IOL placement to give you a clearer outlook on life.

Will IOLs Help Me See Better?

Definitely. IOLs are an essential part of cataract surgery. These amazing medical devices provide our patients with clear, sharp vision once their cataracts have been removed. In fact, some of the intraocular lenses we offer can correct more than one refractive error simultaneously, including:


Overcurvature of the cornea or a longer eyeball can result in impaired distance vision.


Your near vision is compromised when your eyeball is shorter than normal or the cornea is less curved than it should be.


Astigmatism is caused when the cornea or lens is curved too steeply in one direction, causing blurred vision


Farsightedness due to aging is known as presbyopia. This occurs when your natural eye lens loses elasticity.

Types of IOLs

Our Merrillville practice offers three major types of IOLs that can decrease your dependence on glasses or contact lenses. 


A monofocal IOL allows cataract surgery patients to see clearly at a single distance. While monofocal IOLs cannot correct both near and distance vision, they provide a seamless field of view like your natural lens.  


Multifocal IOLs can improve your near, intermediate, and distance vision. However, like trifocal glasses, multifocal IOLs can create a varied field of view with noticeable changes between sections of the lens. 


Toric IOLs are specialized lenses that can treat astigmatism in addition to other refractive errors. Toric IOLs come in both monofocal and multifocal variants, and most major brands carry some form of toric intraocular lenses. 

The IOL Insertion Procedure

First, your surgeon will break up and extract the cataract. An intraocular lens will then be carefully placed to restore your vision.

I went in today for a typical check up after cataract surgery a couple of years back with Dr. Gross. At that time, I had high intraocular pressure and was taking glaucoma-type eye drops to lower that pressure. Dr. Gross suggested iStents at that time and I have been free of eye drops and remain at a normal pressure--no longer glaucoma high. That was a win! Today was another win. My right eye was losing a little clarity due to some growth over the lens after the cataract surgery. Dr. Gross did on- the-spot laser surgery today, and I can see like I did when I was a kid. I can focus on a blade of grass driving down the road!

IOL Placement Steps

IOLs are the only permanent solution to vision loss caused by cataracts.

Procedure Steps

IOLs are the only permanent solution to vision loss caused by cataracts.


We'll start with determining your candidacy for the procedure and discuss which IOL options match your desired goals.


Before starting the procedure, we'll provide numbing eye drops for a more comfortable and relaxing experience.

Cataract Removal 

A small incision is made to gain access to the cataract. Our doctors will separate the clouded lens into pieces and extract it.  


Once the cataract has been removed, we insert the IOL using a minimally invasive tool that transfers a compressed version of the lens to your eye. 


The compressed intraocular lens will unroll and shift into the proper position to replace your natural lens. 

A Doctor with the "absolute highest level of professionalism."

"Dr. Gross has been my ophthalmologist since 1995 and always exhibits excellent clinical prowess and the absolute highest level of professionalism." James Lipton

Questions About Costs or Procedures? We Are Here to Help

Before choosing which type of intraocular lens best fits your vision goals, it is important to determine if insurance coverage is available, and what out-of-pocket costs may be related to premium IOLs.

The friendly doctors and staff at Deen-Gross Eye Centers will listen carefully to your questions during your consultation. We can address concerns about the procedure and your candidacy as well.

What Is and Isn't Covered by Insurance?

  • Cataract surgery is generally covered by all health insurance plans since it's often a medical necessity.
  • The cost of traditional monofocal IOLs can be fully covered in many instances. 
  • Even though premium multifocal IOLs can greatly improve your quality of life, some insurance companies may not cover the cost of premium IOLs because they don't consider multifocal IOLs a necessity. 

Before choosing a type of intraocular lens, it is important to determine potential insurance coverage and the out-of-pocket costs related to premium IOLs. Feel free to contact us to discuss your insurance coverage.

An Investment in Your Quality of Life Are Premium IOLs Worth It?

Premium IOL clarity

A premium IOL has the potential to greatly improve your quality of life, but whether it's worth the price depends on your vision goals. So, ask yourself these questions:

  1. Do I need bifocals to perform simple daily activities?
  2. Am I tired of wearing eyeglasses or dealing with contact lenses?

IOLs are best viewed as an investment in your quality of life. If you answered yes to any of the above questions, premium IOLs can be a worthwhile investment that brings your life into clear focus. 

Frequently Asked Questions  About IOLs

Is IOL placement painful?

Not at all. We can make the IOL placement process pain-free thanks to numbing eye drops. You may feel the sensation of pressure during the surgery, but overall, it's a virtually painless process.

Learn More During a Consultation

Are there any side effects from IOL surgery?

Side effects can occur after IOL placement, but they are usually harmless and go away shortly after your procedure. Side effects may include temporary blurry vision, light sensitivity, dry eyes, and other symptoms that cause minor discomfort. These symptoms should improve day to day, and do not require medical attention unless the side effects worsen or don't subside. 

Read More About Side Effects

Can the IOL get dislocated?

IOL dislocation is rare, and your chances of it happening are significantly reduced when working with an experienced ophthalmologist like Dr. Gross. IOL dislocation doesn't cause pain, but care should be taken to correct the dislocation immediately to avoid further problems, like retinal detachment and intraocular inflammation.

Know the Symptoms of IOL Dislocation

What affects the cost of IOLs?

The cost of IOLs can vary based on several factors, including the type of lens, the experience of the surgeon placing the lens, medical insurance coverage, and more. However, many find that the benefits of seeing clearly without glasses after cataract surgery make the cost of care worth it.

I don't usually leave reviews but Dr. Nelson is an absolute gem! My husband has brain damage and is mostly nonverbal and screams when touched. Medical professionals aren't always nice to him so I was nervous for his first appt but from the very first meeting, Dr. Nelson has been kind, respectful, and patient. He is understanding and works with my husband's limitations. Before cataract surgery, my husband said everything was just black and he can now see things clearly again!!
