Description
Technical field
The present invention relates to the treatment of cataract, more particularly to a kind of raising single focus intraocular lens cataract operation are postoperative de-
The method of mirror rate.
Background technology
Cataract is to cause crystalline lens metabolism disorderly by factors such as aging, heredity, dystrophia, metabolic disorder, wound, radiation
Disorderly, a kind of eye disease caused by crystallins denaturation.Cataract shows as the decline of eyesight progressive, and dazzle is simple eye multiple
Depending on the symptom such as myopia degree increase, seriously affects the daily life of patient.The orally available vitamin C of early cataract, vitamin
The medicines such as B2, vitamin E delay progression of the disease, some mid-term cataract patients, eyesight and phacoscotasmus degree after medication
Certain improvement, but the cataract in maturity period are can obtain, drug therapy, can only operative treatment then without practical significance.Implantable artificial is brilliant
Body is the common approach of surgical cataract, its advantage is that notch is small, and tissue damage is few, and operating time is short, and vision restoration is fast.
Artificial lens is divided into Multifocal intraocular lens and single focus intraocular lens, and multifocal artificial lens can recover preferably to regard
Power, after operation without wearing spectacles can have it is remote in nearly each level visual demand, but Multifocal intraocular lens price compared with
Height, and there is obvious vision to disturb, such as three multifocal intraocular's crystal of Zeiss, Germany, 25,000 yuan or so of price, also solves remote
Eyesight and near vision but the relatively poor Bifocal intraocular's crystal of middle eyesight, region refraction artificial lens, price is 8 thousand to one
13000 yuan are differed, and use constructed single focus intraocular lens price within 6,000 yuan.But single multifocal intraocular
Crystal can only realize single distant vision, middle eyesight or near vision demand, and operation consent is repaiied using target refraction degree as core technology
Just its A constant, artificial lens have certain depth of field, and there are certain adjusting (opposite effect is weaker), and cornea after implantation to regard
Axis area does not wait the increased depth of field such as refractive power, aberration, small astigmatism, so as to inevitably waste part visual range, makes cataract
Eyesight, near vision are bad in most of patients after operation, need to match somebody with somebody mirror and solve, literature search single focus intraocular lens implantation cataract hand
Art takes off mirror rate for 17%.
The content of the invention
The present invention is directed to takes off the problem of mirror rate is low using after single focus intraocular lens progress cataract operation, there is provided Yi Zhongti
The method of the high postoperative de- mirror rate of single focus intraocular lens cataract operation.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
A kind of method for improving the postoperative de- mirror rate of single focus intraocular lens cataract operation, it is characterised in that including following
Step：
1) cataract patient of the single focus intraocular lens of same model is implanted into for operation, is surveyed with defocusing curve method
Its long sight force is measured to distal end and visual range of the eyesight more than 0.8, plus the reserved crystal number of degrees；
2) in total data obtained by step 1), 10% excessive value and 10% too small value is removed, is taken in the range of residue 80%
Minimum value in densely distributed area；
3) step 2) the data obtained input measurement calculate and obtain revised A constants, carried it into it
The corresponding artificial lens calculation formula of numerical value calculates the number of degrees of single focus intraocular lens used in operation；
4) single focus intraocular lens that to select the number of degrees identical or close with the numerical value that step 3) calculates, perform the operation.
Further, calculating is chosen in step 1) is with case condition：Cataract patient is postoperative more than three months, without eye
Bottom disease, does not have severe ocular surface disease, without the big astigmatism of cornea and big higher order aberratons.
Further, step 1) measurable amount is 40-80.
Further, the step 3) measuring apparatus surpass for A, one in Master, Maimonides gram AL-Scan or brilliant star LS900
Kind.
According to the numerical value of revised A constants, can choose SRK-T, HOLLADAY, HOFFER-Q, HAIGIS,
BARRETTUNIVERSALII, OLSEN, PANACEA and SRKII etc. different formula calculates single focus intraocular lens used in operation
The number of degrees.
The beneficial effects of the invention are as follows：The present invention is implanted into same model single focus intraocular lens cataract patient by measuring
Defocusing curve correct the A constants of the model single focus intraocular lens, purposefully choose suitable model list focus people
Work crystal is performed the operation, and solves one of only distant vision, middle eyesight or near vision after single focus intraocular lens implant surgery
The problem of, compensate for the blindness of single focus intraocular lens implant surgery, make patient have at the same time it is good it is remote, in, near vision,
It is not less than 90% using the postoperative de- mirror rate of the present invention.The present invention does not change operation method, does not lift operating difficulty, does not produce more
Remaining expense.
