The patient’s eye axis lengthened but the eye degree did not increase, may be caused by the cornea and lens refractive power decreased, neutralizing the eye axis lengthening caused by the refractive abnormality.
Myopia is not entirely due to eye axis abnormalities, but also has a relationship with the curvature of the cornea and lens. When the patient’s eye axis lengthens, there is also a decrease in the refractive power of the cornea and lens, and the two match, so the patient’s myopia may not change significantly.
Clinically, myopia is also categorized into axial myopia and refractive myopia, depending on the cause of myopia. Axial myopia is more common in clinical practice and is mainly caused by the eye axis exceeding the normal range, while refractive myopia is mainly caused by the cornea or lens curvature being too large, resulting in the refractive power of the eye exceeding the normal range and causing myopia.
It is recommended that myopia patients should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment. Patients should also maintain good eye habits and increase outdoor activities.
