When performing lower eyelid surgery, I usually tighten the lateral canthus (the outer junction of the upper and lower eyelids) to prevent ectropion (the pulling of the lower eyelid away from the eyeball itself). If a patient has an established ectropion (from nerve injury, scarring, age, or whatever), I might tighten the lower eyelid even more with a procedure called a lateral tarsal strip canthoplasty. However, I have never performed this surgery to change someone's "look." The result may be bizarre, and will likely be unnatural. Good plastic surgery should provide natural, stable results. If a patient asked to look like a cat, I would probably turn her away.
