Stability of Biometry in Meibomian Gland Dysfunction

October 12, 2022 updated by: Prim. Prof. Dr. Oliver Findl, MBA, Vienna Institute for Research in Ocular Surgery

Stability of Biometry in Patients With Meibomian Gland Dysfunction

Accurate biometry is an essential and indispensable tool in preoperative cataract surgery setting to yield optimal postoperative refractive outcome. However, some recent studies indicate that preoperative biometry is influenced by dry eye disease (DED). Hence, the investigator's study aims to investigate the effect of the therapy of MGD using the Lipiflow® device on the stability of biometry and selection of IOL.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Accurate biometry is an essential and indispensable tool in preoperative cataract surgery setting to yield optimal postoperative refractive outcome. 31 Patients suffering from DED caused by MGD will be selected and allocated randomly to therapy. Patients with pre-existing DED therapy other than lubricants will be excluded. After completing prestudy-screening and baseline visit, Lipiflow® therapy is applied to the study eye. Follow-up visits will be scheduled two weeks and three months after baseline visit. Each visit includes dry eye investigations and IOL calculation by IOLmaster 700 and CSO MS-39. After each study visit an IOL will be theoretically selected.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 99 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age older than 18 years
  • Evidence of meibomian gland dysfunction
  • Meibomian gland secretion score equal or less than 15 (for 15 glands of the lower eye lid) using the meibomian gland evaluator (see below)

Exclusion Criteria:

  • Usage of eye drops other than lubricants (e.g. antibiotics, steroids, cyclosporin-A)
  • Usage of systemic antibiotic therapy
  • Any pathology of the ocular surface except dry eye disease (e.g. corneal scarring, cornea ectasia)
  • Ocular surgery within prior 3 months
  • Ocular injury within prior 3 months
  • Ocular herpes of eye or eyelid within prior 3 months
  • Active ocular infection
  • Active ocular inflammation or history of chronic, recurrent ocular inflammation within prior 3 months
  • Eyelid abnormalities that affect lid function
  • Ocular surface abnormality that may compromise corneal integrity
  • Pregnancy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
