When highly myopic patients undergo cataract surgery, a certain amount of myopia will be reserved for monofocal IOLs, while multifocal IOLs can be used without reserving a certain amount of myopia.
Highly myopic patients are used to using their eyes at close range in their daily life. If a monofocal lens is chosen for cataract surgery, the lens has no adjustment function and can only restore the patient’s distance vision, and the patient needs to wear spectacles for near vision, which can seriously change the patient’s habit of using his/her eyes. In order to use the eyes more closely to the patient’s preoperative habits, most of the surgical design will retain a certain degree of myopia for the patient.
If the patient chooses a multifocal IOL after cataract surgery, because the lens itself produces multiple focal points for distance, center and near, and the patient can visualize near without wearing a phoropter, there is no need to preserve the amount of myopia. The design of cataract surgery is related to the patient’s own postoperative changes in eye habits, details need to be determined after detailed communication with the surgeon.
It is recommended that patients with high myopia who have cataracts should consult a regular hospital in a timely manner to assess their condition and choose the appropriate treatment under the guidance of the doctor.
