Dr Devgan is an innovator of many cataract surgery tools.
Devgan Axis Marker for Astigmatism Lens Surgery
Some patients have a high degree of astigmatism and they require special toric lens implants at the time of cataract surgery. These toric lens implants much be precisely aligned during surgery and to make this process far more accurate, Dr Devgan designed the Devgan Axis Marker made by Accutome in the USA. This device is now being used by eye surgeons worldwide to provide the best vision for their patients.
A well-known cataract surgeon in England wrote Dr Devgan to congratulate him:
Just wanted to personally congratulate you on the design of your axis marker. Elegant in its simplicity & so easy to use for toric axis marking. Excellent!
Devgan Intraocular Suturing Hook
Dr Devgan has created this delicate instrument for the use in intraocular suturing in complex cases such as repairing an iris defect or suturing an IOL to the back of the iris.
Devgan Micro Capsulorhexis Forceps
The ultra-fine tips of this cross action forceps are ideal for todays small incision procedures, even with sub-2mm coaxial phaco incisions. The mildly sharpened tips allow the surgeon to puncture the capsule without the need to open with a cystotome. By slightly tilting the forceps and entering the capsule with one tip, the surgeon can then close the forceps to securely grab the lens capsule for Capsulorhexis formation.
The iris stop feature allows the surgeon excellent grasp of the capsule without engaging the iris. Gently curved tip follows the intra-ocular anatomical contour and the modified round handle allows for comfortable hand position during the capsulotomy. The cross action handle allows for excellent alignment of the fine tips, reducing wound gape, loss of viscoelastic and AC shallowing. Marks on shafts 2.5mm and 5.0mm from tip end. Manufactured in titanium for durability, and reduced glare and weight. Overall length 119 mm, 4.7 inches.
Devgan Universal Cataract Chopper/ Multi-Tool
A truly universal cataract management tool, allowing multiple functions in one simple and efficient double-ended instrument. Features versatile chopping tip that provides excellent control of the nucleus with all chopping techniques: vertical chop, horizontal chop, tilt-chop, & others. The chopping tip is gently curved and smooth, making it ideal for protecting the posterior capsule from the phaco probe during nucleus removal. The chopping tip features grooves to engage the optic or haptics for IOL manipulation and for iris push-pull in small pupil cases.
The curved tip is also used to lift corneal incision to ease placement of instruments and stabilize the eye providing counter-traction via the paracentesis during IOL implantation, particularly in small incisions. A traditional spatula is provided for intra-ocular manipulation of iris, lens fragments, or if need be, vitreous. Manufactured in titanium for durability, reduced glare and weight. Overall length 137 mm, 5.4 inches.
Devgan Temporal Approach Lid Speculum
This popular lightweight titanium lid speculum has been configured to provide excellent retraction of the lids while keeping the adjustments over the bridge of the nose which keeps the temporal region at the incision free from any obstruction by the speculum.
The screw-type adjustment provides an infinitely variable degree of lid exposure and fitment for all patient types, especially those with deep orbits. The wire arms are thin in order to be unobtrusive and allow the plastic drapes to tuck into the conjunctival fornices. Overall length 86 mm, 3.4 inches.
Devgan Fixation Ring
The off-set design of this instrument ensures the ring maintains it’s level perspective independent of hand positioning and eases placement on the globe. Marks on the top of the ring are spaced 60° on either side of the center of the ring opening which serve as a guide for placement of a paracentesis 60° from the temporal clear corneal incision in coaxial phaco, or for placement of the two micro incisions 120° apart in bi-manual split-irrigation phaco.
The closed side of the fixation ring features marks that are 30° (1 clock hour) apart from each other which serves as a guide for the limbal relaxing incision nomograms that use clock hours of incision length for dioptric correction of astigmatism. Manufactured of durable lightweight titanium. Overall length 117 mm, 4.6 inches.
