Negative intraocular lens anterior chamber implantation

1. Myopic diopter gt; -9.00D, and has been stable for 2 years without development. 2. Those who cannot wear or are not willing to wear glasses and contact lenses due to occupational needs. 3. Height ametropia. 4. Exclude other eye and systemic diseases such as uveitis, glaucoma and diabetes. Treatment of diseases: conjunctivitis glaucoma Indication 1. Myopic diopter >-9.00D, and has been stable for 2 years without development. 2. Those who cannot wear or are not willing to wear glasses and contact lenses due to occupational needs. 3. Height ametropia. 4. Exclude other eye and systemic diseases such as uveitis, glaucoma and diabetes. Contraindications Older, combined with severe heart, liver, kidney and other diseases and difficult to tolerate surgery. Preoperative preparation 1.A ultra-accurate measurement of the depth of the anterior chamber, the axial depth of less than 3mm, the intraocular lens is easy to adhere to the corneal endothelium after implantation, it should be carefully operated. 2. Corneal endothelial cell count, <1000 / mm should not be operated. Surgical procedure The angle-supported ACP-IOL is the same as the normal aphakic anterior chamber intraocular lens implantation. For rigid PIOL, make a corresponding length of limbal incision, inject a viscoelastic agent, introduce a silica gel plate, insert ACP-IOL into the anterior chamber along the silica gel plate, place the anterior crest in the contralateral anterior chamber, remove the silica gel plate, and then remove The sputum is placed in the side angle of the incision, and the skilled doctor can also not use the silica gel plate. The shape of the pupil was observed to confirm that the iris was not involved and the perioral incision was open. Suture the incision. The iris claw type ACP-IOL implantation technique is slightly more complicated. Make a main incision at the top and make an auxiliary incision at 3 and 9 o'clock. After the PIOL is implanted in the anterior chamber, the rotation is horizontal, and the intraocular lens is fixed through a main incision. After the intraocular lens is fixed, a special needle is inserted into the auxiliary incision to provoke a small amount of the mid-peripheral iris at 3 and 9 o'clock. , embedded in the fissures of the intraocular lens. Suction the viscoelastic and suture the incision. For the foldable corner-supported ACP-IOL, the surgical incision can be selected as a clear corneal incision, the other operations are the same. complication eye pain
