Intraocular Lens Calculation

The use of advanced formulas to improve the accuracy of cataract surgery has been a process of ongoing improvement since the 1980s. Today’s leading formula – Holladay 2 – has now been added directly to the IOLMaster®500 device (Carl Zeiss Meditec AG). This will allow a much larger group of surgeons to access the latest formula and should improve both intraocular lens calculation and the resulting visual outcome.

Purpose: To report a case of Exophiala endophthalmitis after cataract surgery, which has not been reported previously in Korea.Case summary: A 70-year-old woman visited the hospital 7 days after cataract surgery in her right eye with unilateral vision impairment. At the time of the visit, visual acuity of the right eye was hand motion, and the fundus was not clearly observed due to numerous inflammatory cells with hypopyon in the anterior chamber. With an initial diagnosis of suspected bacterial endophthalmitis, vitrectomy was performed immediately with intravitreal injection of antibiotics and steroid. On day 14 after vitrectomy, inflammation in the anterior chamber and vitreous opacity worsened, and complete vitrectomy, including of the vitreous base, and removal of the intraocular lens and capsule was performed. Exophiala was detected in the biopsy specimen on day 6 after the second surgery, and the patient was discharged with a prescription for voriconazole eye drops. On day 23 after the second surgery, the best-corrected visual acuity in the right eye had improved to 1.0, and there was no evidence of endophthalmitis recurrence and no observed additional abnormal findings of the fundus until 6 months after second surgery.Conclusions: In a case of fungal endophthalmitis that occurred after cataract surgery, good results were obtained by vitrectomy involving complete removal of the peripheral vitreous body, including the intraocular lens and lens capsule, which was the basis for growth of the fungus in the early stage of endophthalmitis.

Intraocular Lens Calculation

In standard cataract surgery, one of the major goals is to reach target refraction. Based on keratometry measurements, axial length and anterior chamber depth, most of the intraocular lens calculation formulae are suitable to achieve this aim. Further evaluation of corneal refractive parameters like anterior and posterior corneal surface by Scheimpflug devices led to a significant enhancement of precision in astigmatic and post-refractive surgery cases.

Монография посвящена изучению возможностей профилактики послеоперационной спонтанной дислокации комплекса «ИОЛ – капсульный мешок» при выполнении факоэмульсификации в глазах с сочетанием возрастной катаракты и инволюционного подвывиха хрусталика первой степени. Авторами изучены степени тяжести и исходы спонтанной дислокации комплекса «ИОЛ – капсульный мешок» нетравматического генеза после выполнения неосложненной факоэмульсификации, частота инволюционного подвывиха хрусталика первой степени у пациентов с возрастной катарактой перед выполнением факоэмульсификации; технические особенности, интра- и послеоперационные осложнения выполнения факоэмульсификации при инволюционном подвывихе хрусталика первой степени; ближайшая и отдаленная эффективность стабильности положения ИОЛ РСП-3 после выполнения факоэмульсификации катаракты, сочетающейся с инволюционным подвывихом хрусталика первой степени, разработаны показания к выполнению имплантации ИОЛ РСП-3 по собственной технологии и уточнены противопоказания; разработана хирургическая технология имплантации ИОЛ модели РСП-3, обеспечивающая стабильность анатомического положения ИОЛ при факоэмульсификации катаракты, сочетающейся с инволюционным подвывихом хрусталика первой степени, позволяющая минимизировать число спонтанных дислокаций комплекса «ИОЛ – капсульный мешок» в различные сроки послеоперационного периода факоэмульсификации. Книга рассчитана на врачей-офтальмологов, офтальмохирургов, интернов, клинических ординаторов, аспирантов.
