Complete the capsulorhexis of special diameter size), the capsulorhexis reference point multiselect of marking center or femtosecond laser auxiliary is selected as in art after mydriasis
Pupil center's point, the shortcomings that using such method: being on the one hand that the center of pupil and the center of lens capsule bag be simultaneously after mydriasis
It is not exclusively overlapped, even if capsulorhexis technology is very skilled, it is also difficult to realize property capsulorhexis placed in the middle；On the other hand according to pupil after conventional mydriasis
Will appear different degrees of capsule mouth partial center phenomenon after putting capsulorhexis centered on center, before ultimately causing capsule mouth can not 360 ° of complete cycles it is equal
Even covering IOL；Furthermore even if patient attempts subjectivity, by corneal diameter, form selects pouch center as a whole, is selected by subjectivity
It is also higher to select bring error.
Summary of the invention
Many cataract operation doctors are because experience deficiency leads to partial center capsulorhexis, even with existing assistor at present
Tool is also difficult to realize satisfied pouch property CCC placed in the middle, so as to cause IOL can not complete cycle uniform fold, eventually lead to high-end IOL and plant
It is likely to occur bad visual quality after entering and increases the incidence of PCO, so it is an object of the present invention to provide a kind of pouch centers
Position capsulorhexis auxiliary device.
The present invention is achieved by the following technical scheme:
A kind of pouch centralized positioning capsulorhexis auxiliary device, including cornea marking ring, the cornea marking ring are connected by connecting rod

Preferably, two connecting rods are in cross, and crosspoint is cornea marking ring center.
Use process: Preoperative Method is mainly patient under seat state, and patient utilizes 0 ° of -180 ° of level of slit-lamp label
Line determines the accurate location of horizontal corneal diameter with this；Eye speculum opens eyelid in art, after povidone iodine sterilizes conjunctival sac, by device
Trunnion axis overlap with the cornea trunnion axis marked in advance, left and right fine tuning, so that device trunnion axis two sides are beyond corneal limbus
Part is equal, it is ensured that positioning ring (cornea marking ring) occupy corneal surface shape center (pouch center).Cornea is pushed after accurate positioning,
The trace of a diameter 5.5mm is generated in anterior corneal surface at this time, as the guidance of capsulorhexis, there such as have to the position of corneal incision to be special
It is required that (such as: astigmatism IOL implantation), astigmatism IOL cylindrical mirror axle position and corresponding cornea incision site can be marked together, do transparent angle
Film notch and auxiliary incision, viscoelastics tampon anterior chamber, in cornea trace navigation downlink CCCC.
The cornea circular scale disk that the design will be slightly larger than corneal diameter is combined with cornea marking ring, on the one hand it is preoperative
0 ° of -180 ° of horizontal line of seat label under slit-lamp, prevent the eyeball rotation as caused by position chanP in patient's art from causing to mark
Error guarantees that dial is preferably placed in the middle in combination with the scale mark in horizontal position connecting rod, thus more accurate positioning capsule
Bag center；On the other hand the accurate positionin of main notch, loosen notch and auxiliary incision can be provided using dial, can also realized
The orientation direction of astigmatism IOL axle position.Compared with range estimation carries out CCC under routine operation microscope, corneoscleral junction precise positioning is utilized
Pouch center realizes that pouch property CCC placed in the middle, 360 ° of capsule mouth uniform folds after IOL implantation can not only prevent that inverse position method occurs,
And pouch, even if pouch proliferation occurs in the later period, also can guarantee that IOL at a specified future date does not occur biggish shifting to IOL complete cycle uniform force
Position guarantees patient visual's mass.
The present apparatus fully takes into account pouch property placed in the middle to the importance of CCC, using horizontal position corneoscleral junction as pouch side
Boundary's reference more efficiently, simplicity, accurately positions pouch center；It is simultaneously that the central point of capsulorhexis and pouch central point one is a pair of
Answer, realize pouch property CCC placed in the middle, it is final reduce or reduce because patient's individual operations degree of variation is big or (and) experience deficiency causes can
The CCC partial center phenomenon that can occur, improves the postoperative visual quality of patient.Meanwhile anterior capsule periphery uniform fold is remained in IOL
Surface can effectively prevent the generation of inverse position method；Even if later period pouch proliferation because IOL complete cycle by proliferation film traction force it is uniform,
It can also preferably guarantee that IOL at a specified future date does not occur biggish displacement.
Compared with existing auxiliary instrument, the design concept that the present apparatus uses dial to combine with cornea marking ring can root
According to the practical eye anatomical structure of patient, it is accurately positioned patient's pouch center, carries out CCC guidance using cornea marking ring,
The final accurate pouch property placed in the middle for realizing CCC, improves operation accuracy and postoperative effect.
