The TECNIS multifocal lens procedure is generally considered safe, however, as with any cataract surgery or lens implantation procedure there are some risks and potential complications, claims TECNISMultifocal.com. Complications, although rare, include infection, bleeding and worsening of vision. These complications are typically minor and temporary, but in extreme cases can cause permanent effects to vision.
After the procedure, TECNICMultifocal.com advises patients to report any symptoms of complications to their eye doctors immediately. These include pain, itching, severe headache and sensitivity to light. Other symptoms of concern include redness, vomiting, nausea, watery eyes or the appearance of floaters or lights in the field of vision. TECNICMultifocal.com also warns that a small percentage of people request that the implant be removed after surgery.
