During ophthalmic surgeries, having the right surgical scissors that deliver optimal performance is necessary. They ensure accurate and precise cuts with minimal tissue trauma. This reduces the patient's discomfort and ultimately leads to added efficiency.
But can you use any pair of scissors to manipulate both iris and tendon tissues?
Remember, every pair of scissors comes with a unique design specifically manufactured for a certain procedure or part of a procedure.
So, the answer to the above question is no.
Let’s understand the difference between iris and tenotomy scissors in this guide. This will help you pick the right scissors for specific ophthalmic procedures.
What Are Iris Scissors?
As the name suggests, iris scissors are specialized scissors used to manipulate iris in ophthalmic procedures. The main purpose of these scissors is to address underlying issues that may affect the vision.
Typically manufactured from German stainless steel, these instruments can be used for the following purposes:
- Removing a cataractous lens to improve visibility.
- Preparing a corneal bed for a donor during a corneal transplant.
- Cutting or suturing the conjunctiva when performing conjunctival surgery.
- Creating new openings between the iris and glaucoma during iris goniotomy procedures.
- Relieve pupillary block glaucoma by creating small openings in the iris when performing iris iridectomy.
These scissors feature sharp tips and ergonomic handles (that could be in finger-ring or palm-held designs).
What Are Tenotomy Scissors?
Unlike iris scissors, surgical tenotomy scissors are used to cut specific types of tissue found in the extraocular muscles of the eyes, i.e., tendons. These tissues help the eye move in up, down, left, and diagonal positions.
Here are procedures for which surgeons use tenotomy scissors:
- Creating a new drainage pathway for aqueous humor during trabeculectomy.
- Cutting a small opening in the posterior capsule (procedure also known as YAG laser capsulotomy) of the lens after cataract surgery.
- Relaxing or tightening eye muscles for strabismus during muscle surgery.
- Reduce corneal astigmatism by creating small incisions in cornea (limbal relaxing incisions).
The anatomical structure of these instruments features sharp tips for performing precise cuts with minimal chances of complications. They typically come with finger-ring handles that are easy to grasp and handle.
Iris vs Tenotomy Scissors: Overview
Before moving on, have a look at the short summary of the differences between iris and tenotomy scissors:
| Feature | Iris Surgical Instruments | Tenotomy Scissors |
| Purpose | Used for cutting delicate tissues in ophthalmic surgery (e.g., iris, cornea, conjunctiva). | Manufactured for cutting tendons during ophthalmic surgery or other procedures involving tendons. |
| Typical Uses | Iris, cornea, conjunctiva, lens, and other delicate tissues. | Tendons, ligaments, and other tough connective tissues. |
| Size | Generally smaller than tenotomy scissors, as they are designed for delicate tasks. | Can be larger than iris scissors, depending on the specific use case. |
| Blade Shape | Fine, pointed blades with a sharp tip. Can be straight or curved. | Fine, pointed blades with a slight curve. Often have a blunt tip. |
| Handle Length | Shorter handles for better control and precision in delicate procedures. | Longer handles may be used for better leverage in cutting tendons. |
