简要总结

This study is a single center prospective observational case series. The framework of this clinical investigation is post market clinical follow up of pediatric FLACS using the Femto LDV Z8. The intention is to investigate and supervise aspects particular to the pediatric use, and there is hence no alternative patient population.

Primary outcome Related adverse events at the time of surgery, ophthalmic adverse events at 1 week, 1 month, 6 months.

Secondary outcome Achieved vs aimed capsulotomy diameter

  • Aimed diameter to be calculated using the Bochum formula
  • Achieved diameter will be assessed using a ring caliper (Morcher 4.8 external diameter), (US patent MJ Tassignon)

During the recruitment period, the legal representatives of all patients (and when applicable the patients) at the study site who are eligible for pediatric cataract surgery and fulfilling the eligibility criteria will be informed about the study and offered participation. The aim is to include 12 participants during the recruitment period of 6 months. Inclusion criteria are on purpose chosen very broad, in order to collect data from all types of pediatric cataract surgeries.The majority of the participants will be very young children, who cannot be involved in the informed consent procedure. Participants will nevertheless receive the patient information in a way adapted to their age and mental maturity, from investigators or members of the investigating team who are experienced in working with children. The study procedure is cataract surgery performed with the FEMTO LDV Z8 femtosecond laser. In this clinical investigation the CE marked products (the Femto LDV™ femtosecond laser and the FEMTO LDV™ Surgical Laser Procedure Packs for Cataract Surgery) are used without deviations from the intended use and indication for use. Intraoperatively the achieved capsulotomy diameter will assessed using a ring caliper (Morcher 4.8 external diameter) and compared with the aimed diameter calculated using the Bochum formula. Patients will return for follow-up visits at 1 week, 1 month, 6 months after the surgery.
