Centre for Sight has always strived to set the standard for patient care, and part of that standard setting culture is innovation of technology and instrumentation.
We have been involved in numerous developments and influenced changes to equipment and procedures many of which have become popular world-wide. Some have become the gold standard, for care used by other eye-care providers in the UK and beyond.
One of our most recent contributions is in conjunction with Laser Lens and Laser Cataract surgery is the development of an instrument to help remove the centre of the lens. Femtosecond Lasers like Victus, have automated complex components of the cataract and lens extraction process. The Daya Trans-lens Hydrodissection cannula was developed for specific use in Laser cataract / Lens exchange when by chance one of our surgeons noticed the effect injection of fluid had on the lens when injected into one of the lasered openings. An instrument was designed by Mr. Daya and Bausch and Lomb to take advantage of this and the result is a device that reproducibly loosens and breaks up the lens case after case.
The instrument was featured in a peer reviewed publication, international presentation and in an award winning video at the meeting of the American Society of Cataract and Refractive Surgeons in San Francisco in April 2013. Another great first at Centre for Sight!
A new technique for facilitating the passage of riboflavin into the cornea through the epithelium in collagen cross-linking procedures appears to be effective in the treatment of keratoconus and causes less pain and allows faster recovery than the conventional epithelial debridement approach. Developed by Sheraz Daya and Marcela Espinosa and in use since 2005, several hundred procedures have been performed at Centre for Sight. The idea is very simple but has transformed the recovery of patients undergoing collagen crosslinking. The technique developed by Centre for Sight surgeons has been adopted internationally and the subject of peer-reviewed publications.
The instrument originally manufactured by Duckworth and Kent* is now in use worldwide with several presentations and research papers demonstrating efficacy in press. Patrick Condon FRCS, Waterford, Ireland, told a conference of the Irish College of Ophthalmologists; “The new approach to the application of riboflavin to the cornea is called the epithelial disruption technique. It involves first making numerous small perforations inthe epithelium with a device designed by Sheraz Daya”. Read the full article here…
The device and technique was also featured in a round table discussion on CXL published in Cataract and Refractive Surgery Today Europe.
*No longer in production by Duckworth & Kent.

This technique developed by Sheraz Daya while director of both the Corneoplastic Unit at the Queen Victoria Hospital and Centre for Sight. The technique involves cultivating stem cells in the laboratory and then transferring them to the eye surfaces of patients with limbal stem cell deficiency. The procedure hit the international press in 2006 following a breakthrough paper published in the peer reviewed journal Ophthalmology. Katie Piper has been one of the most high profile patients to have undergone this procedure. Read more here…
The forceps are used to grasp the folded donor disc. The two textured platforms hold the tissue at the edge and the space between prevents the tissue from being crushed protecting the endothelium.
A number of instruments where designed with Sheraz Daya (Centre for Sight) and Duckworth and Kent*, including these Lameller Seperator Forceps.

The Daya DSEK Manipulator Hooks are used as a pair to push and pull the donor disk through the paracentesis. The straight shaft allows for a universal tip orientation, as there is sometimes a need to use the tip in the reverse position (tip pointing upwards).
The Daya DSEK Manipulator Hooks are used as a pair to push and pull the donor disk through the paracentesis.
The Daya Descemet’s Scraper has a sharp paddle tip that is angled up from the shaft to scrape the Descemet’s membrane under the cornea. The long 14mm shaft allows the tip to go all the way across the cornea easily.
The Daya Donor Graft Insertion Hook is used to push the donor disk through the paracentesis. The hook automatically disengages from the graft on withdrawal from the eye and can also be used to position the graft centrally.
A number of instruments where designed with Sheraz Daya (Centre for Sight) and Duckworth and Kent*, including the Daya Textured Manipulator.
