    Do's and Don'ts of Managing a Nucleus Drop: A Guide for Beginners

    Managing a nucleus drop during cataract surgery is one of the most challenging and critical situations an ophthalmic surgeon may encounter. While it’s a rare occurrence, its management demands quick thinking, precise action, and a thorough understanding of both anterior and posterior segment techniques. The goals are always to preserve vision, prevent complications, and optimize the long-term outcomes for the patient. Different surveys in India have found the incidence rate of nucleus drop between 0.04-0.1%. (1,2) Dropped nucleus and cortical remnants occur most commonly in phacoemulsification, than other techniques of cataract surgery. (3) Certain conditions associated with posterior capsular or zonular weakness have a higher risk of nucleus drop in cataract surgery. These include the following (4): Pseudoexfoliation syndrome Advanced or intumescent cataract Traumatic cataract Previous intraocular surgeries like vitrectomy or glaucoma procedures Difficult situations like shallow AC, s

    Management of Dropped Nucleus and Retained Lens Fragment

    Introduction: Drooped nucleus and retained lens fragment is a complication not so rare in clinical practice. In the era where cataract surgery is being performed for visual enhancement rather than visual rehabilitation, the management of a dropped nucleus saves the patient from unnecessary anxiety and hastens visual recovery. In this chapter risk factors, the timing of surgery, various approaches for removal of the lens will be discussed. Incidence: Dropped nucleus and cortical remnants occur more frequently in phacoemulsification than other techniques of cataract surgery 1,2 . Surveys in developed nations like U.S and U.K have reported incidences of 0.3 % 1 and 1.1 % respectively. In India, few studies have quoted its incidence to be around 0.8 %. [3] Risk Factors: The exact cause for the posterior displacement of the nucleus is difficult to determine but certain conditions predispose for complication4 Pseudoexfoliation syndrome Traumatic cataract Fellow eye of complicated cataract su

    Scleral Fixated Intraocular Lens Implantation- A Comprehensive Review

    Introduction Ideally a cataract surgery should result in the placement of an intraocular lens (IOL) within the capsular bag. However, this desirable outcome might be averted due to either preexisting zonular deficit or intraoperative posterior capsular tear, resulting in aphakia. This necessitates the need for an alternate means of IOL implantation. The surgeon can exercise the options of an anterior chamber IOL or iris fixated IOL or a scleral fixated IOL. Developments in IOL designs and modifications in implantation techniques have rendered them safe and efficacious. Recent studies have reported no significant differences in the postoperative visual recovery or complications rate between the 3 approaches.1 However, each option should be analyzed not only in accordance with surgeon’s experience but also with patient’s age, local, and systemic comorbidities.2 Scleral fixated IOL (SFIOL) involves sutured/sutureless fixation of the IOL to the sclera. SFIOL’s position closely approximates
