The application of IOLs also has certain restrictions. Not all postoperative cataracts can be implanted with IOLs, and this is especially true for traumatic cataracts, because serious complications will occur after surgery if IOLs are forcibly implanted. Therefore, whether to implant an IOL after traumatic cataract surgery should follow the following principles: 1. After removal of cataract, the posterior capsule membrane is intact and an IOL can be implanted in one phase.
2. If acute trauma causes cataract with intraocular tissue damage, IOL implantation should be considered in the second phase after debridement and suturing, when the local condition is completely stable and the eye can withstand another surgical trauma.
After traumatic cataract surgery, if the posterior capsule rupture is incomplete, the iris is defective or the anterior segment structure is disturbed, but the visual function is still good, anterior chamber or suspension type IOL implantation can be used.
4. For IOL implantation after traumatic cataract surgery in children, it should be carefully selected. For those who are old and have good local conditions, IOL implantation can be performed on a trial basis.
5.IOL implantation should not be performed for traumatic cataracts combined with central corneal white spot, extensive iris adhesions or defects, atrial angle adhesions, highly cloudy vitreous, and fundus damage that seriously affect visual function.
In conclusion, IOL implantation for traumatic cataracts should be carefully selected and should be considered comprehensively according to the patient’s condition before deciding whether IOL implantation is appropriate.
