What are the best cataract surgery questions to ask your doctor?

IN THESE TOGGLES YOU WILL FIND THE ANSWERS YOU ARE LOOKING FOR

The use of femtosecond lasers within cataract surgery is becoming more common.

Femtosecond lasers are used to minimise the use of surgical blades and needles providing precision and micron accuracy.

The femtosecond laser constructs the wound and then breaks up the cataract in approximately 50 seconds allowing the surgeon to extract the broken up cataract and introduce the artificial lens.

Laser cataract surgery (or, more accurately, laser-assisted cataract surgery) is fairly new and significantly increases cataract surgery cost, primarily because the laser machine is very expensive. While studies have shown that lasers can improve accuracy during the procedure, they may not necessarily improve cataract surgery safety, recovery time and visual outcomes in every case.

Prior to cataract surgery it is important to have a thorough consultation with your optometrist or ophthalmologist. They will perform a comprehensive eye exam to check the overall health of your eyes and evaluate whether there are reasons why you should not have surgery and identify any risk factors you might have. They will ask you about your occupation, hobbies and lifestyle to ensure expectations are attainable.

A number of tests and scans will be performed including a refraction which is similar to what you have done at an optician. This will accurately determine the amount of short-sightedness, far-sightedness and/or astigmatism you have prior to surgery.

Additional measurements such as the curvature of your cornea and the length of your eye will be taken to help your surgeon decide upon the appropriate power of IOL to place inside your eye to gain the best possible outcome for you.

Today you have many types of IOLs to choose from for your cataract surgery depending on your specific needs.

In addition to IOLs being able to correct near-sightedness and farsightedness there are now Toric IOLs used correct astigmatism.

Astigmatism is when your cornea is shaped similar to a rugby ball rather than a round football, if astigmatism is left uncorrected, it can distort your vision and you will not be entirely satisfied with cataract surgery results.

A Monofocal IOL will correct either your distance or your near vision. In most cases, people wish to correct their distance vision and are happy to remain wearing reading glasses.

Alternatively you can have two slightly different powered lenses to give you some distance correction and some reading correction, this is called monovision.

Monovision can be simulated through contact lenses and a quick trial is required to see if you can tolerate the difference.

Some people may have certain conditions whereby a Monofocal IOL is better suited, i.e. due to occupation, previous eye surgery or certain eye or medical conditions.

A Multifocal IOL is designed to provide an increased range of vision after cataract surgery than standard Monofocal IOL. It works by splitting light enabling you to have multifocal functionality and can eliminate or reduce the use of glasses completely.

Multifocal IOLs tend to be a popular choice for those with presbyopia.

Eye Clinic London’s preference of Multifocal IOL are the Trifocal lenses and the extended range of vision lenses. Both have proven safety and efficacy but your surgeon will discuss with you which one will suite your eyes, your particular needs and lifestyle.

Both Multifocal and Monofocal IOLs are available in a Toric type.

Toric IOLs can be used to correct moderate to high levels of astigmatism, they work by being placed in a specific position to counter the astigmatism

You can expect to be at the surgical centre for 90 minutes or longer. To begin with, the nurses will prepare your eye using drops to dilate your pupil and numbing the surface of the eye. Thereafter you will be taken into the surgery room where surgery typically takes 15 minutes.

A clear eye shield is placed over the eye to protect it in the early stages of your recovery, you will be advised to keep the plastic shield over the operated eye every night for one week. Thereafter, you will be taken into recovery where your post-op drops and medications will be explained.

You must have someone drive you home after cataract surgery; do not attempt to drive until you have visited your eye doctor/optometrist the day after surgery and he or she has tested your vision and confirmed that you are safe to drive.

You must wear your protective eye shield while sleeping or napping for about a week after surgery.

While your eye heals you might experience some eye redness and blurred vision during the first few days or even weeks following the procedure.

During at least the first week of your recovery it is essential that you avoid strenuous activity and heavy lifting, bending, exercising and similar activities that might stress your eye while it is healing, and water that might splash into your eye and cause infection.

Keep your eye closed while showering or bathing. Also, avoid swimming or hot tubs for at least four weeks and any activity that would expose your healing eye to dust, grime or other infection-causing contaminants.

If you have any questions or concerns about cataract surgery be sure to discuss them with your eye doctor and cataract surgeon prior to signing “informed consent” documents authorising surgery. Be sure to advise your surgeon of all medications you are taking, including non-prescription (“over-the-counter”) formulations and nutritional supplements. Some medications and supplements can increase your risk of cataract surgery complications and might need to be discontinued prior to surgery.

Your cataract surgeon may give you other instructions and recommendations for your cataract surgery recovery depending on your specific needs and the outcome of your procedure. If you have any questions at any time after cataract surgery your surgeon will be happy to answer these.
