Trends and Market Share of Presbyopia-Correcting Intraocular Lenses in Taiwan & Asia

賴俊杰 Chun-Chieh LaiTaiwan Speaker Trends and Market Share of Presbyopia-Correcting Intraocular Lenses in Taiwan & Asia In this section, we will talk about the trends and market share of presbyopia-correcting intraocular lenses in Taiwan and Asia.Minimize Further Dehiscence of Zonules in Patients with Large Zonular Weakness Zonular weakness increases the likelihood of dealing with complicated cataract surgery and encountering postoperative complications. These risks include intra- and postoperative complications from cataract surgery, such as posterior capsular rupture, vitreous loss, and lens dislocation and decentration. Common risk factors for weak zonules are pseudoexfoliation syndrome, mature cataracts, high myopia, Marfan syndrome, and prior ocular surgery. Signs of weak zonules include iridodonesis, phacodonesis, abnormal anterior chamber depth or asymmetry, angle asymmetry on gonioscopy, and vitreous in the anterior chamber. Zonular dehiscence and lens subluxation or dislocation can be seen in advanced zonulopathy. But most of the time, weak zonules may not be noticed until after the surgery has begun. Intraoperative signs of weak zonules include anterior chamber depth fluctuation, difficulty puncturing the anterior lens capsule, star-shaped striae on the capsule surface during the capsulorhexis, lens movement when manipulations, and difficulty in rotating the nucleus within the capsular bag despite adequate hydrodissection. In this video discussion, we will talk about how to minimize further dehiscence of zonules in patients with large zonular weakness during operation and make the cataract surgery safer.
