Application of artificial lens: The artificial lens is a special lens made of synthetic material. The shape and function of the artificial lens is similar to the lens of the human eye, which enables external objects to be focused and imaged on the retina to see things around. Recently, a series of new IOLs have been introduced, bringing a boon to cataract patients.
Classification of artificial lens: 1.Hard IOL: The material is hard and the surgery will cause a certain degree of astigmatism, which will cause a greater reaction and longer recovery time in the short term.
2, ordinary folding IOL: soft foldable material, small surgical incision, no sutures required after surgery, can reduce or avoid corneal astigmatism, light postoperative reaction, short recovery time.
3.Aspheric IOL: Closer to the physiological state of the human eye, it can correct the spherical aberration of the eye and improve the imaging quality, especially to improve the contrast sensitivity at night.
4.Adjustable IOL: The material used is similar to or better than the material used for folding IOLs, the difference is that the adjustable IOLs can see far, in and near. The first three IOLs can only see near or far, which is a single function. At present, most domestic use Fluorovision adjustable IOLs, and the clinical effect has been widely verified with high patient satisfaction.
5.Adjustable aspheric IOL: On the basis of providing patients with the function of seeing far, in and near, it further improves the imaging quality and makes the post-operative visual quality more perfect.
Patients are advised to choose the appropriate IOL according to their financial situation and communicate fully with their doctors.
