LASIK laser eye surgery
We've been performing laser eye surgery at Moorfields for 22 years. Over 4000 cases in 2016
LASIK was first performed in 1992 and has become the commonest type of laser eye surgery performed worldwide. The success of LASIK is due to its excellent visual results and rapid visual recovery and minimal discomfort after surgery.
LASIK first involves making a very thin flap in the front of the cornea. The flap is carefully lifted and the excimer laser is then used to precisely reshape the underlying cornea to focus light precisely into the eye. The flap is then gently replaced and a contact lens bandage is placed over the flap to protect it. This is removed the following day.
When LASIK was first developed the flap was made using a special blade called a microkeratome. Since 2003 however, another type of laser called a femtosecond laser has been used to create the flap. The femtosecond laser allows the surgeon to very accurately choose the exact position and thickness of the flap to within 1/1000 of a millimetre.
The risk of complications is also significantly reduced when using a laser rather than a blade. The femtosecond laser used at Moorfields is the newest generation of Intralase femtosecond laser.
At Moorfields Mr Angunawela only performs Intralase LASIK (IntraLASIK). It's the safest, most predictable form of LASIK and there is no point in compromising on these standards. Mr Angunawela also only performs Wavefront treatments on all cases as standard for the best quality of vision.
The American Society of Cataract and Refractive Surgeons have published a review of over 1500 studies on laser eye surgery published over the last 10 years and found that over 95% of people were happy with this type of surgery.
IntraLASIK is a surgical procedure and like any type of surgery there is a small risk of complications. Not all patients are suitable to have LASIK surgery, either due to very high prescriptions, their general health of thin corneas. Some patients experience dryness of their eyes, reduced night vision, glare and infection after surgery. These symptoms are usually temporary. The risk of losing your sight due to laser eye surgery is very, very small. The risk of having a reduction of best corrected vision after LASIK is less than 1/1000, which is a low risk for a surgical procedure and no more than the cumulative risk of wearing contact lenses for a few years. Thorough pre-operative screening and examination of your eyes will reduce the risk of potential complications. You can also reduce these risks by choosing a consultant surgeon that is trained in corneal surgery and that has been appropriately trained to perform vision correction surgery, and who uses the most cutting edge technology. Your eye surgeon should discuss these risks with you and also alternatives to laser eye surgery at your initial consultation.
Certain patients may not be suitable for LASIK. If you practice full contact martial arts, boxing or are in the police or military, or have thin corneas you may be better suited to a surface laser eye surgery such as LASEK.
Do tell your doctor if you have rheumatoid arthritis, diabetes, keratoconus or are pregnant.
Make sure that you're well informed and don't be afraid to ask questions.
