Patients with vision loss to 4.5 need to identify the cause of the disease and treat the cause of the disease, such as medication, surgical treatment, prescription lenses, etc., in order to improve visual acuity, but may not always be able to improve to 4.8, the specific prognosis is related to the patient’s condition.
Under normal circumstances, the naked eye visual acuity of adults can reach 5.0, and the current visual acuity of 4.5 is below normal. If refractive error causes vision loss, such as myopia, hyperopia, astigmatism, etc., the patient can use optometry to clarify the specific degree, and then wear appropriate glasses to correct the refractive error and improve vision.
Cataracts are also a common cause of vision loss. Patients can undergo surgery to replace the cloudy lens inside the eye with a clear IOL to improve vision.
Patients with keratitis can also experience vision loss due to clouding of the cornea. Patients can follow the doctor’s instructions to use medications such as tobramycin eye drops and levofloxacin eye drops to control inflammation and improve vision. However, if the patient’s cornea forms a scar, blocking the light, it is more difficult to improve the patient’s vision.
It is recommended that patients with vision loss consult a hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
