LASIK laser eye surgery

At the forefront of developments in technology, Mr Mearza published a study evaluating and comparing modern excimer lasers used in laser vision correction.

He was the first surgeon to publish results of LASIK laser eye surgery using a combination of the Ziemer femtosecond laser and the Wavelight Allegretto excimer laser, two of the most technologically advanced lasers available on the market today. The published results are amongst the best in the world for laser vision correction.

Out of 887 short-sighted (myopic) eyes undergoing laser eye surgery treatment, 96.9% of eyes achieved 20/20 vision after the operation. When both eyes were considered together, 100% achieved 20/20 vision after their laser vision correction surgery.

There were no significant complications with any of the patients treated either during the operation or after surgery.

corneal transplantation corneal transplants

Corneal transplantation

In 2007, Mr Mearza published the first UK series of patients undergoing a new partial thickness corneal transplantation technique (endothelial keratoplasty).

He also presented the results at the American Academy of Ophthalmology Meeting in the USA.

The technique has since been modified further and Mr Mearza is amongst an elite group of surgeons who offer the new and improved technique which allows for faster visual recovery and healing.

The new technique called “DMEK” involves transplanting a 15 micron thick piece of tissue into the eye.  You can watch a shortened version of the DMEK corneal transplantation technique to understand more about this procedure.

Charity work

Giving people back their sight back is one of the most rewarding aspects of my job. It’s incredibly humbling and truly an honour to be involved in this kind of work

Mr Mearza has a strong interest in charitable ophthalmic work and has been on numerous trips abroad helping some of the world’s most needy people see again.

His interest in charitable work began in 2001 with a visit to India. This was followed by subsequent trips to Bali, Burma, Madagascar, Bangladesh, Ghana and Cambodia restoring sight to patients afflicted with cataracts.

Although some of the places visited and the environments are challenging, this is offset by the huge rewards and gratitude that come with giving people their eyesight back. You can see a diary of some of the trips he’s been on here.
