Hypothesis: The RAVI-Guide provides superior patient acceptability to the conventional lid speculum during intravitreal injections

Aims: To compare patient acceptance and procedural complication rates of the RAVI-Guide with those of the conventional lid speculum and caliper approach

Inclusion Criteria:

• Patients age 18 years or older who undergo intravitreal injection for clinical indications.

Exclusion Criteria:

• Patients under the age of 18 years
• Patients unable to give informed consent
• Disorders that preclude the ability to judge pain or discomfort associated with intravitreal injection
• Disorders that preclude the ability to assess for complications of intravitreal injection
• Inability to assess the landmarks by which localization of intravitreal injection sites is determined, such as obscured corneal limbus
• Inability to communicate directly to the physician and immediately after the procedure the level of pain or discomfort
