STEP 3. Getting the eyes ready for surgery
The surface of your eye needs to be as smooth and healthy as possible. All pre-existing dry eye needs to be treated. This improves your recovery following cataract surgery, and most importantly, it improves the quality of eye measurements obtained by laser scanners. I am very proactive about treating dry eye before cataract surgery, as this improves my patients’ vision, comfort, and speed of recovery.
STEP 4. Eye Measurements
The dimensions and curvature of your eye must be precisely measured. This is done using a laser scanner (optical biometry) and a high definition camera (corneal topographer). The power of the lens implant your eye requires is calculated using these measurements.
STEP 5. Calculation of Lens Power
There is special lens calculator software which will takes your eye measurements and determines the best lens power for each eye. Of the wide range of lens calculators available, I use the most sophisticated “4th generation calculators”, with my own computer algorithm.
Obtaining perfect measurements and selecting the best possible lens for each eye is fundamental to premium cataract surgery. I have published scientific research articles on this process.
STEP 6. Surgery
Cataract surgery is performed in a day surgery as a walk-in, walk-out procedure. You are positioned on a bed and your eye is completely numbed with anaesthetic drops. Intravenous sedation is given as a “twilight anaesthetic”. The vast majority of patients have no recollection of the surgery!
I use a variety of different cataract surgery techniques to optimise the result. Usually, I will make two tiny, keyhole incisions: the largest is only 2.2mm wide. The incisions are so small that they seal with a watertight closure, without the need for stitches.
The new artificial lens implant is rolled up and injected through the incision. It opens up inside the eye to rest inside your natural lens capsule. I then rotate the lens implant, so that it aligns precisely with the optics of the eye. To do this, I use an image guidance system projected inside the eyepieces of my surgical microscope.
The entire procedure takes approximately 15 minutes.
Optimal surgical technique is highly ritualised to minimise the risk of complications, and to produce highly consistent results.
I will check on you after the surgery before you go home.
STEP 7. Post-operative Eyedrops
Medicated eye drops are used for four weeks to help the eye to heal. Several brief check-ups are performed in clinic during this time. If glasses are required, these can be updated four to six weeks after cataract surgery.
