Hydrogel hydrophilic multifunctional high simulation soft prosthetic eye, it contains water, oxygen permeable has the function of absorbing and slowly releasing the eye drops. It improves the utilization rate of drugs, reduces the number of eye drops, shortens the recovery process after prosthetic table implantation, and utilizes the suction cup effect without nailing and good rotation. Why did rigid prosthetic eyes need to be pinned in the past? It is because the patient’s prosthetic eye does not rotate well or does not rotate at all after wearing it. Therefore, a hole is made in the implanted prosthetic table, a titanium steel tube is inserted, and a titanium steel nail with a convex cap is inserted into the tube. A pit of the same shape and size as the cap is made in the same area of the back of the prosthetic eye as the titanium steel nail, and the titanium steel nail cap, which protrudes from the conjunctival surface, is used to force the prosthetic eye to rotate. Because the titanium steel nail is gently put into the titanium steel tube, so there is a certain gap between the nail and the tube, the eye in the up, down, left, right rotation at the same time, the lower edge of the titanium steel nail cap and the upper edge of the titanium steel tube produced grinding, this part of the conjunctival sac is easy to hurt, in daily life it is difficult to sterilize the titanium steel tube, so the inner cavity of the titanium steel tube has become a breeding ground for germs, the conjunctiva is easy to be infected once injured. Hydrogel hydrophilic high simulation soft prosthetic eye uses suction cup effect to adsorb on the eye, which reduces the friction between the prosthetic eye and the eye and improves the comfort, and also avoids the foreign body feeling when wearing the hard prosthetic eye (there are other materials that are especially slippery and fragile), which can easily lead to lower eyelid drooping and deformation when worn for a long time, and cannot be connected by the patient’s own tissue, so that the prosthetic eye cannot rotate synchronously with the healthy eye. The disadvantage is that the prosthetic eye cannot rotate in sync with the healthy eye. Hydrogel is the most ideal prosthetic eye at present.
