Intraocular lens – Inserting a Guide Lens

Inserting a guide lens

A guide lens is a tool used to insert a new lens into an eye. It is typically comprised of a flexible body portion 22 and a flap portion 24 that is connected to the lens by a connecting portion 26. Guides are usually made of thin, flexible materials, such as metal or plastic. They are typically four millimeters wide and about 40 millimeters long. The material used to make the guide is approximately 0.003 inches thick.

Intraocular lens 10

The present invention is directed to a double barrier intraocular lens with a ledge and an annular ledge that extends about the optic and into the posterior capsule. The ledge provides a relaxed transition space and capture area while preserving the integrity of the double seal. The ledge also comprises a plurality of loops that secure to the optic and the posterior capsule at a distance of 0deg to 10deg. 하이안과

In addition to the optic, the intraocular lens can have one or more haptics. The haptics may be attached to the optic by various mechanisms. The most common configuration has two diametrically-opposed haptics that provide a means of fixation and optimal centration for the implant.

Intraocular lens insertion guide 20

An intraocular lens insertion guide 20 is a medical device that is used to facilitate the insertion of the intraocular lens into the capsular bag of the eye. It comprises a flap portion and a body portion. The flap portion is attached to the body portion by an integral connecting portion. The flap can move from its first position in which it is folded against the body portion to its second position, which acts as a backstop for guiding the lens into the eye. The insertion guide 20 is made of a thin flexible material, such as plastic, metal, or a combination of these materials. The flap portion is preferably made of a material that is about 0.003 inches thick.

The guide 20 is inserted into the eye through the incision 12. The lens is then placed into the eye through the flap portion 24 of the lens. As the lens is being inserted through this flap portion, the iris 4 and the capsular bag 8 hold the flap portion 24. The remaining intraocular lens insertion surgery steps are well-known.

Intraocular lens insertion tube 32

The invention relates to an intraocular lens insertion device. The insertion device includes a generally tubular main body 11 and a push rod and threaded sleeve. The push rod has a taper portion 15 that deforms the intraocular lens 1 during insertion. The insertion tube 17 projects from the tip end of the main body 11, while a holding member 18 is fixed to the tip end. 렌즈삽입술

This insertion device is designed to allow for consistent pressure to be applied to the IOL during the procedure. This prevents the lens from slipping during insertion and also minimizes sudden starts. The insertion device has a plunger rod assembly that is in communication with the inserter housing.

Surgical instruments used to insert intraocular lens 10

Surgical instruments used to insert intraocular lenses are essential during cataract surgery. These instruments are made of stainless steel and are used for making small incisions around the eye. They are useful for performing procedures such as cataract extraction and evisceration/enucleation. These instruments have blunt tips and can be used to create an angled incision.

Surgical instruments for implantation of intraocular lenses vary widely in their shape, size, and functions. Some are specially made for a particular type of tissue and are used to manipulate various types of ocular tissues. The handles, tips, and shafts of these instruments are designed for specific purposes. The handle has knurling or serrations to facilitate proper placement. Most of these instruments are six-sided and are made of stainless steel. Surgical instruments made of titanium are less likely to be curved or have large serrated surfaces.

Procedure for inserting a guide lens

Inserting a guide lens involves making a small incision in the eye’s cornea, right in front of the natural lens. The procedure is quick and painless, and afterward, a protective pad is placed over the eye to prevent infection. If possible, have someone drive you home afterward, as you will not be able to function properly while your eye heals.
