What is the cut of cataracts?
During the cataract operation, the eye lens is removed and replaced by a clean artificial lens. In order to perform this operation, the opening must be created by an ophthalmic surgeon called Cataract. It is made on the cornea side and is used to remove cataract and introduce a new lens.
The size of the cataract cut is usually determined by an ophthalmologist before the surgery. Different types of cuts used for cataract surgery generally range from approximately 0.078 inches (2 mm) to 0.472 inches (12 mm). The determination of the appropriate cut size depends on several factors, such as the cataract itself, the removal technique and the type of material used in the substitute lens.
Cataracts are usually removed by means of a procedure called Fakoemulsification. This method uses a tool that disintegrates and then sucks the cataract from the eye. When performing this particular form of surgery cataractyexterly small cut, which is usually 0.118 inches (3 mm) or less. This is generally large enough to make umoThe tool and a spare lens in the eye.
The distribution of cataract for removal may not be possible in some cases, especially if it is an older or denser cataract. In these situations, a procedure called Extracapsular Extraction of Cataract (ECCE) is performed. The surgeon will have to create a cut of cataracts, which is up to 0.472 inches (12 mm). The cut of this size allows the surgeon to remove the entire cataract.
The substitute lens material is also a determining factor in cataract cuts. They will usually use three types of lenses that ophthalmologists usually use: silicone, acrylic or lens made of a material called polymethylmethakrylate (PMMA). Both acrylic and silicone lenses can be folded and can be inserted through a very small section of cataract, such as a cut used for fakoemulsification. The PMMA lens is not moving and requires a larger cut to be inserted into the eye.
After surgery, cataract cuts or may not require stitches. Very small cuts are often self -service and are left to close themselves. Larger slices of cataract often require the use of stitches to close the wound and are removed later.
