Cataract Surgery and Implant Options

Cataract Evaluation

If you have been previously diagnosed with a cataract or if you feel you are experiencing blurry vision, a comprehensive eye examination is important.  The examination can determine if the cataract is the source of your visual complaints.  If the cataract is the source of your complaints, we can complete a cataract evaluation and discuss with you the options.

Most people develop a cataract as they get older.  Surgery is recommended when the cataract is interfering with your day to day activities.  Patients may experience difficulty driving especially at night or in the rain and bright sunlight.

A comprehensive eye examination involves checking your visual acuity, refracting to see if new eyeglasses can improve your vision, a slit lamp examination and a dilated examination.  Dr. Stanley Grandon and I will also take a comprehensive medical history.  This is done to assess for any conditions that would increase the risk of a problem during surgery.

If  the cataract if the cause of your visual complaints, Dr. Stanley Grandon and I will discuss with you the risks and benefits of surgery as part of the cataract evaluation.  We will take the time to discuss implant options with you.  For example, if you have astigmatism you may be a candidate for a toric implant to correct the astigmatism.  If you have a desire to be less dependent on glasses for near activities, you may be a candidate for a presbyopic implant that allows some vision for near and intermediate activities.

Cataract Surgery Implants

When I first trained, monofocal intraocular implants were primarily used.  Most patients still required glasses after their surgery due to either astigmatism and/or near vision needs.

Many patients have astigmatism and benefit from a toric intraocular implant.  I discuss the option of this implant with all patients who have corneal astigmatism.  It reduces the dependence on glasses after surgery.

Multifocal implants can help correct vision both at distance and for near activities.  These intraocular implants can work well for patients who wish to be less dependant on glasses for both distance and near and intermediate vision.   To determine which implant is best for you, it is important to understand your visual needs.  For example, do you wish to have better intermediate or reading vision?  Are you willing to accept that you may have decreased contrast sensitivity or some halos at night?

The extended depth of focus implants (Symfony) corrects vision provides more of a continuous vision by using an extended range of focus technology.  This lens will be a good option for patients who have a desire to be less dependent on glasses for all activities.  You may still need a low power reading glasses for some up close activities.

When Do I Adopt New Technology?

Changes in Intraocular Implants

As a comprehensive ophthalmologist, my primary surgery is cataract surgery.  The methods and technology used for cataract surgery are constantly evolving.  For example, in the past, patients had to wear very thick eyeglasses after cataract surgery.  This is no longer necessary since intraocular implants became available.  When I completed my residency training, almost all intraocular implants were monofocal.  This means they only correct vision for one distance.  If the intraocular implant is corrected for distance, the patient still needs glasses for computer and reading.  Over the years, much new technology has been developed.

New TechnologyCataract Surgery | Intraocular Implants

It is important that I stay educated on new technology that is developed.  I focus on technology that is relevant to my practice.  I educate myself by reading peer reviewed journal articles, articles regarding experiences of other doctors, and attending local and national conferences.  I also discuss with colleagues their experiences.

I use the information I learn to gather my own opinion on the value of the new technology.  It is important that I feel it is safe for my patients and that it will offer an improved outcome.  I often wait a few months after the technology is approved by the FDA to learn from the real world experience of other ophthalmologists.

Initially when I implement a new technology, I may try in in a very select group of patients.  I evaluate the results before proceeding with a larger group of patients.

Multifocal implants can help correct vision both at distance and for near activities.  These intraocular implants can work well for patients who wish to be less dependant on glasses for both distance and near.  I am cautious about recommending these intraocular implants due to the potential for decreased contrast sensitivity and difficulty with night driving.

The Symfony implant corrects vision provides more of a continuous vision by using an extended range of focus technology.  This lens will be a good option for patients who have a desire to be less dependent on glasses for all activities.  It does not run the same risk of halos and glare.

Staying Educated

It is important that I continue to learn and evolve the technology that I utilize.  This will provide my patients with the best outcomes possible.

What to expect with cataract surgery

What to expect with Cataract Surgery

Now that you are ready to have cataract surgery what can you expect?

Cataract surgery is an outpatient operation often performed at ambulatory surgical centers.  Dr. Stanley Grandon and I perform ours at the Dearborn Surgical Center. cataract surgery

Preparation for Cataract Surgery

We ask you to instill drops for the 3 days prior to your surgical date.  One of the drops is an antibiotic and the other is an anti inflammatory drop.  You typically cannot eat or drink for several hours before the operation.  When you arrive at the Dearborn Surgical Center, we ask that you bring a driver with you.

When you arrive at the surgical center you will be asked to change into a gown.  You will receive medication to dilate the pupils and be seen by the anesthesia staff.  During the operation you will feel no pain.  You will receive sedation to make you comfortable.  In most cases, surgery is performed without a numbing injection.  Surgery usually takes less than 20 minutes.

After your Cataract Surgery

After your cataract surgery you can expect the vision to be a bit blurry as the eye heals and adjusts.  Most of the time cataract surgery does not require a bandage.  It is normal to feel a scratchy or foreign body sensation in the eye.  Dr. Stanley Grandon and I will have you continue the antibiotic drop, the anti inflammatory drop and we will add a steroid drop.  It is very important to continue to use these drops as directed after your operation for the eye to heal properly.

Post Op Visits

You can expect to come in for a check up to our office the day after your operation.  We ask you to bring your drops with you for that visit.  Most day to day activities can be resumed immediately.  You will then return to our office approximately one week after your operation and then at one month.  If necessary, we can perform surgery on your other eye 1-2 weeks after the first eye as long as the first eye is healing well.  A prescription for new glasses (if necessary) will be given at your one month post op visit.

Scheduling Cataract Surgery

If you decide to schedule the cataract operation, we will take measurements to determine the implant type and power to use.  The entire cataract evaluation can take approximately 2 hours time.  You will read and sign informed consent paperwork.  Our surgical schedulers will provide prescriptions for drops to be used before and after cataract surgery.  They will go over all of the details of what to expect the day of your operation.  You will need to have a driver bring you to the Dearborn Surgical Center on the day of your surgery.
