What are the risks associated with intraocular lens implantation surgery?

After intraocular lens implantation surgery, possible complications may include infection and inflammation, elevated intraocular pressure, lens dislocation, corneal damage, and postoperative glare. Most of these complications are controllable, and risks can be reduced through standardized surgical procedures and proper postoperative care. If persistent eye pain, sudden vision loss, or abnormal discharge occur after surgery, prompt medical attention is recommended.

1. Infection and inflammation: If the surgical wound is exposed to pathogens or postoperative care is inadequate, ocular infection may develop, causing symptoms such as redness, swelling, pain, and increased discharge. Severe cases may impair visual recovery.

2. Elevated intraocular pressure: Factors such as improper lens positioning or obstruction of aqueous humor drainage may lead to a sudden increase in intraocular pressure, resulting in eye discomfort, headache, nausea, and other symptoms. Prolonged high pressure may damage the optic nerve.

3. Lens dislocation: Vigorous activity, trauma, or inadequate fixation during surgery may cause the implanted lens to shift or dislocate, leading to blurred vision, double vision, and other symptoms, requiring timely intervention and correction.

4. Corneal injury: Corneal endothelial cells may be damaged during surgery, or postoperative corneal edema and inflammation may occur, manifesting as dry eyes, foreign body sensation, and fluctuating vision, which can affect visual quality.

5. Postoperative glare: Differences in lens optical design or pupil adaptation issues may cause glare or halos around lights, particularly under bright lighting or at night, reducing nighttime visual clarity and affecting safety during nighttime activities.

After surgery, it is essential to strictly follow medical instructions regarding medication, avoid rubbing the eyes, and maintain ocular hygiene. Exposure to intense light and strenuous physical activity should be avoided in the short term, and screen time should be managed appropriately. A light, easily digestible diet rich in vitamins is recommended to support tissue repair and promote eye recovery.
