re of the anterior corneal surface must A: be flattened. B: remain unchanged. C: be steepened. 2. Er:YAG lasers are not suitable for the treatment of caries because of A: cytotoxicity. B: low efficiency. C: thermal effects. 3. Angioplasty with excimer lasers is likely to induce A: atherosclerosis. B: restenosis. C: thermal injury. 4. In stapedotomy with Er:YAG lasers, the fluence should be limited to A: 1 J/cm2. B: 10 J/cm2. C: 100 J/cm2.
Lasik and PRK both methods are used to treat hyperopia farsightedness. The PRK treatment is mostly common in Europe. The curvature of anterior corneal surface is flattened during the surgery.

The distance of the laser tip to tooth must be kept at least 10 cm to avoid thermal damage to the teeth.
