Brief Summary

This study collects intra- and postoperative data from the patients´charts retrospectively and evaluates retro- and prospectively the rate of posterior capsule opacification (PCO) following implantation of the intraocular lens L 313.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Eyes With Posterior Capsule Opacification Following Implantation of IOL 313 up to 8 Years

    In order to find out whether patients with cataract surgery are affected by lens opacification, we assessed whether a Nd:YAG laser capsulotomy was performed for treatment. For this purpose, the patient files were spotted first. Those who had no recent findings were asked in writing if and when a laser treatment was performed. In the absence of feedback and in case of uncertain or unusable written answer, a telephone consultation with the patient was made. If sufficient information was not available afterwards, the ophthalmologist was asked for information (by phone, by written request or by collecting the data on site in the practices).

    up to 8 years

Secondary Outcomes (1)

  • Correlation Coefficient Between Capsulotomy Rate and Parameters

    up to 8 years

Study Arms (1)

Implantation of IOL L313

Patients who have undergone a cataract surgery with implantation of the monofocal MICS IOL L313 more than 3 Years ago will be asked about the Treatment for Postoperative observation and survey.

Other: Postoperative observation and survey

Interventions

For postoperative Observation with a survey we ask the patients (or in case of no information the ophthalmologist) whether they had undergone a YAG-Laser-Capsulotomy after Cataract-Surgery or not.

Implantation of IOL L313
