- Tests performed by Woodhams Eye Clinic to provide the best posssible vision:
- Refraction Test: EPIC-5100.
- Biometric Test: LENSTAR.
- Ultrasound Test: A-Scan.
- Retinal Imaging: Optical Coherence Tomography (OCT)
- Optical Quality Test: Optical Quality Analysis System (OQAS)
When should you schedule a cataract surgery?
If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery. When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended.
Are both eyes done at the same time for cataract surgery?
Even when a patient has cataracts in both eyes, it’s common for surgeons to perform cataract surgery on one eye first. A second cataract surgery will be performed on the other eye not long afterward.
Do you need pre op clearance for cataract surgery?
Routine preoperative medical testing should be avoided in patients undergoing cataract surgery, particularly when surgery is performed more than 30 days after biometry, to reduce costs as well as inconvenience for patients and clinicians, researchers say, according to a report from Reuters.
When to use an ocular ultrasound for cataract surgery?
This measurement helps the cataract surgeon determine the best intraocular lens power and type for that particular eye. Ocular ultrasound is also used to exam the inside of the eye, especially when the doctor’s view is blocked by an opacity like a damaged cornea, a thick cataract or a hemorrhage inside the eye.
How long does it take for cataract surgery to take place?
During surgery, the doctor will remove the cloudy lens from your eye and replace it with an artificial lens (called an intraocular lens). The surgery lasts about 1 hour and is almost painless. Usually, you will be awake during cataract surgery.
Do you need a vision scan before cataract surgery?
This provides the best outcome. Patients who wear soft contacts usually take about a week without contact lens use to unmold, and rigid gas permeable contact lens wearers take about a month. Is the “A” Scan covered by insurance? Yes, an “A” Scan is always needed before cataract surgery, so it is covered by insurance.
How are biometric exams used in cataract surgery?
Furthermore, the biometric examination will follow as part of your pre-operative examination, where we will measure your eye and the results of the measurement will be used as entry parameters for the calculation of your new artificial intraocular eye lens, which will be implanted into your eye during the cataract surgery.

How long does it take to get a cataract removed?
Fortunately, surgery to remove cataracts is generally safe and highly effective. In almost all cases, cataract surgery is an outpatient procedure that takes around 20 minutes. During the procedure, an eye surgeon removes the clouded lens and replaces it with a plastic lens implant.

What do you need to know about a cataract scan?
This “A” Scan device measures the length of the eye in addition to the shape of the surface of the eye, and the dimensions of other structures in the eye.
