Intraocular Lenses

An intraocular lens (IOL) is inserted during cataract surgery to replace a damaged lens. These lenses can provide various benefits.

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

What can today's advanced IOLs achieve?

A Tailored Treatment Can Optimize Your Results

Dramatically Improved Sight

Our practice, serving Hobart and Merriville, IN, use IOLs to replace the eye's damaged natural lens and restore clear vision, allowing you to reduce or stop using your contact lenses or glasses.

Personalized Solution

An in-depth evaluation will be performed to determine which type of IOL will best correct your eyesight. Some lenses can even correct the effects of astigmatism.

What does the procedure entail?

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

Are IOLs typically successful?

Most Patients Are Happy with Their Results

The same percentage of patients also said they would choose to have the same lens re-implanted again.

What conditions can IOLs help address?

Simultaneously Correcting Refractive Errors 


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.


When the cornea or lens is curved too steeply in one direction, it can cause blurred vision. 


Farsightedness due to aging is known as presbyopia. This occurs when the lens loses elasticity.

An Essential Aspect  of Cataract Treatment

First and foremost, IOLs are used as a vital component of cataract treatment. These medical devices make it possible for patients to see again once their cataracts have been addressed.

Surgery may sound scary, but you're in good hands...

Safe Treatment Performed by  Board-Certified Surgeons

Many patients are concerned about safety and comfort when seeking treatment for cataracts. However, IOL implantation along with cataract removal surgery has one of the highest success rates among all surgical eye treatments.

Our exceptionally well-trained eye surgeons have performed over 40,000 cataract surgeries collectively. Dr. Deen, the founder of Deen-Gross Eye Centers, was the first surgeon in the county to use IOLs in combination with cataract surgery. In regards to discomfort, anesthetic eye drops are used to reduce sensitivity during treatment. Additionally, IOLs are made of a flexible material designed to fit comfortably over your natural lens.

What type of IOL do you need?

Meet Your Unique Goals with the Right IOL 

We offer several types of IOLs to accommodate your needs:

Monofocal ACRYSOF® IOL
This technologically advanced implant allows cataract surgery patients to see more clearly at a distance. However, patients often still require the use of optical aids even after surgery.
AcrySof® ReSTOR® IOL
This innovative lens improves your near vision, intermediate vision, and distance vision. It often eliminates the need for visual aids like glasses after surgery. ReSTOR IOLs are used to improve cataract patients' vision as well as those who want to correct the quality of their eyesight.
AcrySof® Toric IOL
This type of IOL is specifically designed to improve astigmatism in cataract patients. Toric lenses may minimize the need for corrective lenses following surgery.

Patients can expect a fairly simple procedure...

IOL Placement During Cataract Surgery


Once the cataract has been removed, the IOL will be inserted using a special tool.


The lens will be unrolled and shifted into the proper position within the lens capsule.
Machine to fit IOLs and contact lenses
A distinct advantage of our Zeiss IOLMaster 700, the most advanced machine in its field, is that it captures high resolution calculations of the cornea allowing for optical outcomes for IOL's and contacts.

If You Are in Search of a Fantastic Doctor...

“I had bad vision for the past few years due to cataracts and was getting worse. [After surgery] that same day I was able to see things I haven't been able to see in quite awhile. For a small fee he gave me 20/20 vision and was able to go on without glasses anymore. If you are in search of a fantastic doctor look no further, Dr. Gross can make it happen for you.” Jason H.

How Much Do IOLs Cost?

Cataract surgery is generally covered by all health insurance plans and the cost of traditional IOL implants is also fully covered. However, some insurance companies do not cover the costs associated with ReSTOR® because these elite, special-featured IOLs aren't typically viewed as strictly a necessity.

Before choosing which type of premium IOL best fits your needs and desires, it is important to discuss the cost related to the treatment and concerns your have regarding surgery. We are more than eager to address all of our questions and have an in-depth conversation about what to expect before, during, and after surgery. We offer care credit financing options for qualified candidates who are seeking treatment through IOLs at our Merrillville and Hobart, Indiana eye care centers.

An Investment in Your Quality of Life

Although standard IOLs are typically covered by insurance, they are limited when compared to premium lenses. In order to determine whether this investment is right for you, ask yourself:

  • Would bifocals be necessary to perform your favorite activities?
  • Do you mind relying on corrective eyewear on a daily basis?

If the answer to either of these questions is yes, speak with your doctor about what premium lenses could do for you. The added investment could give you much more freedom and satisfaction in your everyday life.
