Clear corneal incision for cataract after glaucoma surgery

0 months), Henan Medical Information puncture injection of viscoelastic room forward, circular anterior capsule tear,[link widoczny dla zalogowanych], if the pupil margin and posterior capsular adhesions were cut with a diameter of about 51111II ring cut off the central anterior capsule, phacoemulsification cataract . Expand the corneal incision, posterior chamber intraocular lens implantation, posterior capsule tear ring in some cases, replacement of viscoelastic aspiration, clear corneal incision with a 10 1 0 nylon suture needle. Fluid from the incision into the balance and restore the anterior chamber. Check the first 3 days after dressing,[link widoczny dla zalogowanych], the first 4 days from optometric vision test, and 1 week after surgery, two weeks, a month to do optometry dynamic visual tracking observed. 1.3 Results The postoperative visual acuity following table. Wrapped with the naked eye after vision correction or spherical spider + '1 days 4 days 2 weeks 1 month - a Shai 0.05). 5 cases of corneal edema in the first postoperative day, mean intraocular pressure measured T +2, intravenous injection of hypertonic agents, 1 times / day, 3 days after the intraocular pressure returned to normal intraocular pressure after l weekly average 2.0lkPa. 2 discussion ① postoperative cataract glaucoma is relatively common in clinical, if the intraocular pressure is well controlled, and the filtration channel to maintain normal, then the traditional incision can not continue to be used, or below the temporal limbal incision is a methods. But surgery should be considered when the original case of iridectomy filtration surgery, such as a cut above the iris root or total,[link widoczny dla zalogowanych], shall be considered the side of the iris, but would not affect the delivery of nuclear l1 take this group of records produced somatic phacoemulsification, no delivery of nuclear process, but two hands is not convenient. The clear corneal incision surgery more in line with the general habit, easy to operate, combined with phacoemulsification instrument to solve the small incision,[link widoczny dla zalogowanych], delivery of nuclear difficult problem. ② corneal incision at the top level of the limbus in 1.5mrn, sneak 2mrn forward from the top of the limbal incision about 3.51111II, depending on when the level of the upper eyelid covered. Do not block the formation of the light, there is no monocular diplopia. Does not affect the corneal incision and the anterior chamber angle structures, surgical instruments into the anterior chamber of the undercut part does not touch the iris, the maintenance of normal intraocular pressure filtration channel does not cause damage. 2J ③ the level of clear corneal incisions on astigmatism after a stable, basic and preoperative similar. Because as the incision edema, tissue counterparts. Scar formation, relaxation sutures, corneal curvature stabilized J. 1 dose level of corneal incision,[link widoczny dla zalogowanych], as is the trapezoidal incision, closed for good together, suture traction force smaller impact on the corneal changes in the vertical meridian small l4J. So the first day after surgery in some patients already achieve the desired visual acuity. ④ As the group were all patients after glaucoma surgery, preoperative corneal astigmatism surgery has been the existence of different levels, and the early onset of visual function has been damaged to varying degrees when, after it has low vision or corrected visual acuity is expected. In short, the clear corneal incision does not hurt the conjunctiva and sclera tissue to retain the original anti-glaucoma surgery channel function J, the level of stealth cut, easy operation, closed after a good period in the regeneration of corneal tissue organization in compliance with the Law of Correspondence 1 month after the change has become more stable corneal curvature by surgically induced corneal astigmatism has become the preoperative level + on the impact of visual acuity can not afford a decisive role. Therefore, implantation of foldable intraocular lens in the unconditional case is a clear corneal incision level 6mrn glaucoma patients after cataract surgery an effective manner.
