This comprehensive course will give you the fundamental knowledge needed to begin performing cataract surgery by phacoemulsification and extracapsular removal. Each step from preoperative evaluation to postoperative care will be covered to help prepare you for the operating room.
Cataracts remain the leading cause of visual impairment and blindness worldwide. The development of this course was an effort to make learning to perform cataract surgery more accessible to trainees in the US and worldwide. The course teaches the fundamentals required to perform successful phacoemulsification and extracapsular cataract surgery. Expert cataract surgeons will lecture on each step of cataract surgery from preoperative assessment to postoperative care. Lectures will explain the “how-to,” pitfalls, and successful execution of each part of cataract surgery. Surgical video is included to demonstrate optimal performance of various steps. More advanced topics such as small pupil, astigmatism, and capsular complications are also reviewed. Since most cataract surgeries are done with the patient awake, it is imperative that the surgeon gains as much knowledge as possible prior to entering the operating room.
1. Describe proper technique for performing cataract surgery, from wound construction to wound closure
2. Evaluate a patient with cataracts in preparation for surgery and determine the appropriate anesthetic to use
3. Know how to identify potentially difficult cataracts and list appropriate strategies for complicated cataract surgery
4. Understand intraocular lens calculations, forumlas, and selection
Unit 1: Prior to the Operating Room
This unit describes what needs to take place prior to getting the patient to the operating room. Although this unit may seem trivial, knowing when to make the decision to do surgery, having a good informed consent discussion, selecting an intraocular lens and anesthetic type are critical to a successful surgery and happy patient.

Unit 2: In the Operating Room and Getting to the Cataract
This unit begins in the operating room after the patient is prepped and draped. It covers each step needed for you to access the lens. Once you begin operating, you will realize that each step of surgery has a domino effect. If the beginning steps are not done skillfully, it will make the rest of the case more difficult.

Unit 3: Removing the Cataract and Intraocular Lens Placement
This unit is where all the fun begins. The lectures cover lens and cortex removal. We also discuss intraocular lenses and their insertion into the eye. While lens removal is the most critical step of surgery, it is also where the most serious complications occur, so pay attention!
