Early Anesthesia vs Standard Anesthesia, MCS vs ReLACS, Pain Perception Postoperatively First Eye vs Second Eye
Conditions
Brief summary
The focus of this study is to assess how pain can be mitigated for patients undergoing cataract surgery through the early application of anesthesia prior to the surgery as compared to the standard timing, and by using the ReLACS cataract surgery technique compared to the standard MCS technique.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain Perception between Manual Cataract Surgery and Refractive Laser Assisted Cataract Surgery | 1 year | The pain scores will be measured using the Visual Analogue Scale (VAS) which is based on a 0 to 10 scale. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Effects of Early vs Standard administration of neurolept anesthesia on pain perception | 1 year | The pain scores will be measured using the Visual Analogue Scale (VAS) which is based on a 0 to 10 scale. |
| Differences in pain perception between first eye vs second eye | 1 year | The pain scores will be measured using the Visual Analogue Scale (VAS) which is based on a 0 to 10 scale. |
