Intraocular lens (IOL) by Dr. John W. Murrell

Cataract surgery has become very high- tech, quick, usually pain free, very effective with very good to excellent results that can last a lifetime. Technology has scientifically increased the precision and safety of cataract surgery and provided many options for patient’s postoperative vision. The cataract patient today has many options to choose from depending on their lifestyle and how much independence they want from glasses. Let’s review these IOL options so that you can make a well thought out decision on your vision based on your lifestyle and needs. I have chosen the Alcon company headquartered in Fort Worth, TX for the IOL’s that I use. I would like you to choose the IOL that is best for you and your lifestyle. There are 4 types of IOL’s available. The most common patient with monovision is a near sighted person who has one eye corrected for distance vision with a contact lens (CTL) while the near vision in the other eye has no correction. Those patients can choose to continue the monovision when they have the cataract surgery with one eye corrected for a distance focal point and the other eye corrected for near. This will reduce the need for glasses. Patients in my experience are usually very happy after cataract surgery. However, monovision will usually only be offered to those who have tried monovision previously and who have liked it for years. The monofocal IOL is covered by insurance and has no out-of-pocket cost to you. Contact us today for a consultation

The conventional monofocal

(The conventional monofocal)

Corrects vision in one focal point (when you see the best without glasses) this can be at distance (most common), near, or intermediate.

  • 25% of patients may still need a weak pair of glasses at a focal point that they choose (usually distance.)
  • 100% of patients will need for the 2 focal points that they did not chose.
  • You will need reading glasses 100% of the time if you choose a distance focal point.
  • You will need distance glasses 100% of the time if you choose near focal point.
  • There are few patents that have mono vision prior to cataract surgery. Mono vision is when one eye sees well at a distance and the other sees near.

Acrysof IQ Toric Lens

(The conventional monofocal IOL with astigmatism)

Almost every eye has some astigmatism. This occurs when the clear cornea in the front of the eye is irregularly shaped. Those patients with very minimal or mild astigmatism do not require this IOL. However, those patients who have moderate to severe astigmatism may choose this IOL so they can see better at the focal point they choose (usually distance).

  • 25% of patients may still need distance glasses
  • 100% of patients will need reading glasses
  • Remember, this is a premium IOL and there is an out-of-pocket cost to you.

  • 5% of these patients may still need distance / intermediate glasses while 85% will not need distance or intermediate glasses.
  • 50% of the patients may see ok at near with good lighting, while 50% of the patients will need reading glasses.

  • This IOL design may give glare or halos of light at night (in my experience less than 5%). While many patients have this, very few are bothered by it.

Learning as much as you can about these choices prior to your evaluation in my office will help you ensure that you get the type of vision requirements that you desire. There is also much more detailed information on the internet regarding these IOL’S and I encourage you to check them out.
