How is cataract surgery done? Many patients are still fearful of cataract surgery. With the development of technology, cataract surgery has become a very mature and safe surgery. As shown in Figure 1: You can see a very thin and clear capsule wrapped around the cloudy lens. The surgery is performed to preserve the clear capsule and aspirate the cloudy crystal cortex inside. Generally, the surgeon will make two small incisions at the edge of the cornea, and the instrument will reach into the eye through the small incisions and tear a circular slit in the transparent capsule so that the instrument can reach the cloudy crystalline cortex. The cloudy cortex is removed by ultrasound emulsification, which greatly reduces the operative time. Looking at Figure 2, the surgery preserves this very thin transparent capsule, which acts like a plastic bag to hold the IOL. The IOL is placed very securely in the capsular bag and is easy to manipulate. If there is a problem with the capsular bag itself, the procedure can become complicated and the operation can take longer.

Cataract surgery can significantly improve the patient’s visual experience. As shown in the picture, the patient sees the bouquet of flowers blurred before the surgery, but after the surgery, he sees a bright and clear picture of flowers. This is why many cataract patients feel better after surgery and their quality of life is greatly improved. Some patients are even pleasantly surprised to find beautiful things that they could not feel in their cataract state, such as the dark flowers on the wallpaper in their homes. What are the factors to be considered in the development of the surgical plan? Although cataract surgery procedures are becoming shorter, they are still risky internal eye surgeries and the design of the surgical plan has a clear impact on the patient’s post-operative vision. When dealing with a patient, we cannot only examine the cataract, but also check the patient’s cornea, fundus and intraocular pressure, ask about the patient’s general condition and oral medications, etc. to get a comprehensive understanding of the patient’s ocular and physical condition. Before making a cataract surgery plan, the doctor should consider the following factors: whether the patient has keratoconus, glaucoma and fundus disease; whether the patient has farsightedness, myopia, astigmatism, etc.; whether the patient with systemic disease has serious blood disease, immune disease, renal insufficiency or malignant tumor, etc.; whether there are oral anticoagulants and other systemic medications that may affect the surgery; in short, the doctor should consider the patient’s ocular and systemic conditions as a whole to make an optimal plan. All in all, the surgeon has to consider the patient’s ocular and systemic conditions as a whole to develop an optimal surgical approach to obtain the best postoperative results. The cataract surgery plan should also take into account the patient’s needs and the patient’s life and work status, so that the surgery will allow the patient to feel the best in his or her life and work status. There are a variety of cataract types, and individual differences between patients are more complex than we might think. Therefore, before performing cataract surgery on a patient, the ophthalmologist must not focus solely on the cataract, but must fully consider the patient’s ocular and systemic conditions in hopes of improving the quality of the patient’s vision through the surgeon’s expertise. In the eyes of our doctors, each patient is unique and will take the patient’s needs very seriously to develop a surgical plan that is best for the patient.
