title: Pre-surround division technique: precise cracks surrounding the posterior opacity prior to phacoemulsification in posterior polar cataract surgery.
abstract: Three methods are currently used for posterior polar cataract surgery: intracapsular cataract extraction, posterior approach, and anterior approach. A high level of skill is required to divide the lens in the anterior approach, and few studies have investigated safer or simpler division methods. We focused on the division method in posterior polar cataract and developed a pre-surround division technique that divides the nucleus and avoids the posterior opacity. This technique creates precise cracks that surround the posterior opacity prior to phacoemulsification and does not cause intraoperative complications, resulting in successful intraocular lens implantation in all eyes. This pre-surround division method is a safe and easy technique that can be used in patients with posterior polar cataract.
