The prospective observational case series of Dr. Cesar G. Espritu and Dr. Juanchito P. Bernardo, Jr. has been published in the Journal of Cataract and Refractive Surgery. The article entitled: Incisional sizes at different stages of phacoemulsification with foldable intraocular lens implantation  can be found in J Cataract Refract Surg 2009; 35: 2115-2120. Their article evaluated incision sizes during the different stages of phacoemulsification and after implantation of a foldable acrylic intraocular lens. They recommend that an incision of 2.3 mm at the start of surgery may prevent wound tears and surface irregularities.
