Abstract
The invention relates to an artificial intraocular lens capsular sac adopting loop filaments for intraocular fixing, which comprises a capsular sac part and loop filaments for fixing. The capsular sac part is a transparent sac consisting of a front capsular membrane and a rear capsular membrane. The center of the front capsular membrane is provided with a hole. Small holes are also distributed on the front capsular membrane. More than one loop filaments for fixing are distributed in a central symmetry manner. Body parts of the loop filaments are provided with expanded parts. The artificial intraocular lens capsular sac can be used for treating aphakia without the intraocular lens capsular sac.
Description
Technical field
The present invention relates to a kind of artificial intraocular lenses's capsule bag, specifically, relate to and a kind ofly make the fixed artificial intraocular lenses's capsule of ophthalmic bag with button loop silk.
Background technology
Cataract is common oculopathy, needs the artificial intraocular lenses is fixed in the capsule bag of natural lens by the form that button loop supports in the cataract therapy process.Pathological changes, wound or postoperative complication may cause lenticular capsule bag or fixedly the Suspensory ligament of capsule bag is impaired, thereby the artificial intraocular lenses can not be implanted in the lens capsule bag.
At present when lens capsule bag or Suspensory ligament are impaired can't carry out that the artificial intraocular lenses implants in the capsule bag time, fixedly the artificial intraocular lenses mainly contains several modes: method of clamping and suture fixed form:
Method of clamping is the different aspects that the artificial intraocular lenses are attached to tissue, holds such as iris clamping artificial intraocular lenses or artificial intraocular lenses's capsule sackholder, and it is slightly difficult that this mode is operated the supporting way of fastening with a rope, string, etc., and needs specific tissue and exist and can finish.If, then can't carry out when lens capsule bag or Suspensory ligament damage when serious.
The suture fixed form is suture will be passed the tissue back by toe-in artificial graft's thing to be fixed, this mode requires low to the integrity of tissue, but enclosed space within the eye knotting is unusual difficulty, and the operation technique difficulty is big, operating time be the button loop supporting way ten surplus times.
Summary of the invention
The technical problem that will solve of the present invention provides a kind of artificial intraocular lenses's capsule bag, it penetrates scleral walls by the fixed mode of button loop silk, with the elasticity of button loop silk and the part of expanding artificial intraocular lenses's capsule bag is fixed on the scleral walls, thereby has avoided suture to fix this class complicated operation operation.
For solving the problems of the technologies described above, artificial intraocular lenses's capsule bag of the present invention comprises capsule bag part and fixing with the button loop silk, wherein:
