Feature Products >> Moorfields Safe Surgery System with new adjustable sutures
Prof Peng T Khaw
A complete set of instruments for a system of glaucoma surgery known as the Safe Surgery System that has evolved at Moorfields Eye Hospital in London. The safe surgery system’s development is based on a need to improve the consistency. The use of strong antimetabolites such as mitomycin C (MMC) during trabeculectomy increases the risk of potential complications, including hypotony with visual loss and leaking as well as uncomfortable blebs that may lead to endophthalmitis. The Safe Surgery System is designed to preserve visual acuity by minimizing hypotony and bleb-related complications while achieving a desirable postoperative.
Duckworth and Kent have, in collaboration with Professor Peng T Khaw from Moorfields, developed a series of instruments specifically for the Safe Surgery System.

The following video has been kindly been made available and narrated by Prof. Peng T Khaw
WARNING: Videos may contain actual surgery footage;
this can be graphic and unsuitable for some people.

Khaw Glaucoma Surgery Speculum (9-576) have a central indent and side notch to achieve maximal exposure for glaucoma surgery and minimize pressure on eye.
The Khaw Conjunctival Clamp (2-686) holds and protects the conjunctival edge during antimetabolite application.

Khaw Small Descemet Membrane Punch (7-101) is Particularly suited when small sclerostomy required (e.g. thin sclera, small scleral flap)


The tips of the Khaw Transconjunctival Adjustable Suture Control Forceps (2-502) highly polished for massaging and adjusting intraocular pressure to desired level.
