IOLs can be implanted in trauma patients with retinal defects if the macula is functioning normally and the corrected visual acuity can be improved. However, if the patient’s vision cannot be improved by IOL implantation, further lens implantation is not recommended and may result in worsening of the eye injury. Traumatic eye injuries may result in partial retinal loss, and the impact on the patient’s vision is related to the size and location of the retinal loss. Small retinal defects in the periphery may only cause damage to the visual field and may not have a significant impact on vision. If the patient’s macular retina is functioning well and the corrected visual acuity can be improved by optometry, then the patient may be eligible for IOL implantation. However, if the patient’s macular retina is severely damaged and the corrected visual acuity cannot be improved, there is no need to implant an IOL, which may also lead to eye loss and further vision loss. It is recommended that patients with traumatic eye injuries seek prompt medical attention to evaluate their condition and follow the doctor’s instructions.
