Rotational Stability of a Hydrophobic Acrylic Plate Haptic Intraocular Lens Using a Capsular Tension Ring - An Intraindividual Comparative Study

Rotational Stability of a Hydrophobic Acrylic Plate Haptic Intraocular Lens Using a Capsular Tension Ring - An Intraindividual Comparative Study

Recruiting
45-95 years
All
Phase N/A

Overview

The present study should investigate the influence of a capsular tension ring on postoperative rotational stability of a plate haptic hydrophilic acrylic intraocular lens. All patients will be operated on both eyes in one occasion. Both eyes receive a Zeiss 409MP plate haptic intraocular lens, while only on eye receives an additional capsular tension ring. Follow up visits take place 1 hour, 1 week, 1 month and 4 to 7 months after surgery. At the follow up visits, the actual IOL axis will be determined by retroillumination photography. IOL centration and tilt will be determined by anterior segment SS-OCT Casia II. IOLs will be implanted in 4 different axis 0 +/- 10 degrees, 45 +/- 10 degrees, 90 +/- 10 degrees, 135 +/- 10 degrees. IOL rotation, decentration and tilt then will be compared intraindividually.

Exclusion Criteria:

  • Corneal abnormality (Corneal scaring)
  • Preceding ocular surgery or trauma
  • Uncontrolled glaucoma
  • Proliferative diabetic retinopathy
  • Iris neovascularization
  • History of uveitis/iritis
  • Microphthalmus
  • Recurrent intraocular inflammation of unknown etiology Uncontrolled systemic or ocular disease
  • Pregnancy
  • Lactation

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
