All the patients underwent phacoemulsification with monofocal foldable intraocular lens(IOLs) implanted through a 2.8-mm superior corneal incision. The anterior corneal wavefront aberrations for the 6.0-mm pupillary diameter was measured by i Trace wavefront aberrometer(Tracey Technologies, Inc.) preoperatively and 1 month postoperatively. Changes of root mean square(RMS) values of Z(3,-3), Z(3, 3), Z(3,-1), Z(3, 1), and Z(4, 0) and total high order aberration(HOA) were evaluated.Results: The uncorrected and corrected visual acuities improve significantly(P<0.001). No significant postoperative changes were observed in spherical aberration(P=0.652). Significant changes in vertical coma and vertical trefoil(0.005±0.214 vs.-0.049±0.242, P=0.037;-0.141±0.222 vs.-0.258±0.359, P=0.001; separately). However, the total HOAs increased after cataract surgery(0.567±0.161 vs. 0.688±0.343, P<0.001).Conclusions: Corneal vertical coma and vertical trefoil changes significantly in 2.8mm superior corneal incision phacoemulsification cataract surgery. In addition, those had a trend to negative direction.展开更多

Methods From January 2012 to January 2013, 15 patients underwent primary bilateral retromuscular breast augmentation with round textured silicone-gel implants and a novel infra-nipple broken line incision. Preoperatively, a semicircular incision was marked along the inferior base of the nipple. It was then extended bilaterally using two transverse right-angled geometric broken lines within the pigmented areolar skin. Follow-up was performed to evaluate the sensation of nipple-areolar complex, the scar, and the shape and texture of the breasts. Results The average follow-up was 6.7 months. Most of the patients complained of paresthesia of the nipple or breast skin, but transient decreased sensation improved within 3 months. No patients showed permanent sensory changes of the nipple areolar complex at a minimum follow-up of 4 months. The scars were imperceptible in all patients. Conclusion We believe that for selected patients, the infra-nipple broken line incision is a practical and reliable method to achieve aesthetic result.展开更多
