A Revolutionary Technique of Tescuing Capsulorhexis Radial Tear-out with the Use of Cystotome

Part 1: Purpose

The main purpose here is to demonstrate complex technique of a capsulorhexis radial tear out rescue with the use of cystotome in a human eye and on a cataract surgery simulator (virtual reality).

Part 2: Method

Here is a list of steps to be applied immediately after the initiation of a capsulorhexis to veer radially to the periphery beyond the pupillary margin:

Step 1 – Immediately stop capsulorhexis manoeuvre. Also re-examine the whole situation.
Step 2 – The anterior chamber should be filled with OVD (ophthalmic viscosurgical device).
Step 3 – Mount cystotome to a syringe filled with OVD. This helps reinflation of anterior chamber.
Step 4 – It is now time to leafe the capsulorhexis flap unfolded on the surface of lens.
Step 5 – Tilt tip of cystotome horizontally. This will avod puncturing or cutting of the flap. It will be engaged on the flap.
Step 6 – Look at the leading edge of tear and push or pull it right opposite to its direction.
Step 7 – The above step will make leading tearing edge do a ‘U-Turn’. The surgeon should maintain tension on the flap. This should be done until the return of tearing to the desired trajectory.

Part 3: Results

Use of this technique will help a surgeon respond immediately to radial tear out sans changing important surgical instruments. Switch of instruments at this point may be a risky affair. It can tear radial through sudden anterior chamber shallowing due to forward pressure ccoming from the vitreous. This technique ensures minimizing corneal wound distortion in conjunction with following collapse of anterior chamber.

Part 4: Discussion

The EYESI Surgical Simulator serves as an effective and realistic training platform for surgeons (novices and experienced). It helps them practice varied complex techniques of capsulorhexis tear-out. The most significant part of implantation process of endocapsular intraocular lens and phacoemulsification. It is also the most complex part of the process. Success of any cataract surgery depends on achievment of efficient capsulorhexis.

Surgeons may face a tough time while uundertaking the capsulorhexis. A common challenge is a radial tear-out. Hence, it is crucial for surgeons to gain detailed knowledge and acquaintance about tackling the problem promptly sans making the condition worse. Although there are many ways of rescuing situation through the use of capsulorhexis forceps, using an EYESi surgical simulator is the quickest and more effective.

How Cataract Surgery is Performed

Cataract surgery has turned out to be quite an easy procedure these days. The credit goes to advanced technology and introduction of latest tools and equipment in the medical industry. A patient is referred to specialist (precisely an ophthalmologist) prior to surgery. The specialist will assess the problem before proceeding. Thereafter, the eye care team will take measurements of eyes. This is done to analyze the overall strength of artificial lens replacing natural lens of patient.

Here, the patient can have a detailed discussion about the cataract surgery and get answers for any queries they may have in mind.

Cataract for Both Eyes

Under this condition, the surgery will be conducted in two different sessions. The duration gap between two sessions is usually 6 weeks to 12 weeks. This is important to give the operated first eye ample time to heal. By this time, the vision of patient also returns to normal. Another benefit is for the surgeon who can easily assess and determine the latest glasses prescription for the first eye.

The Cataract Surgery Procedure

Cataract surgery is a common procedure for eye treatment. The straightforward surgical procedure takes around 30 to 45 minutes. Patient is usually administered local anaesthetic. This keeps patient awake during the procedure. They are allowed to go home the same day. Phacoemulsification is the most common surgical procedure for cataract.

Prior to the operation, the nurse will put drops in patient’s eye to dilate (widen) pupil. Thereafter, local anaesthetic in the form of eye drops. Sometimes, anaesthetic is also administered as an injection into the tissue around the eye.

Post dilating pupil, the surgeon will create a minute cut inside cornea (located in the front of eye as a transparent layer). The next step is to insert a small probe emitting ultrasound waves through cornea into the eye. This helps in breaking affected lens into some pieces. The surgeon will liquify and suck the pieces out. Another probe is given to suck the leftover pieces out of exterior lens.

The surgeon inserts a plastic lens soon after removal of the affected lens which is curled up in an injector. Thereafter it is injected through cut made initially inside the cornea. Once in place, the lens unfolds and takes natural position of the old lens.

In some cases, surgeons may require making larger incision to replace affected lens. This cuts needs to be closed with minute stitches. The surgeon will remove the stitches after around a few weeks later.

Replacement of Lenses

Once the affected cloudy lens is removed through surgery, it is replaced with a new lens. This artificial lens is referred to as an intraocular implant (IOL) and made from clear plastic.

Types of IOL

Three different types of IOL are available for patients these days:

The Fixed Strength Lenses (Monofocal) – These lenses are set for one level of vision used for distance vision. The lenses are common among most of cataract surgeries.

The Multifocal Lenses – These lenses can be easily set at two or more variety of strengths, mainly distance and near vision.

The Accommodating Lenses – These lenses facilitate the eye to focus on near as well as distant objects. This is done in the same way as in a natural lens.

Use of accomodating or multifocal lenses can significantly minimize overall chances of patient requiring reading glasses post surgery. However a lot of patients may require wearing glasses under some situations post surgery regardless of the lens type fitted on their eyes. These lense are not usually available on the NHS. Hence, patients should consult their ophthalmologist about availability of the lens type in their area prior to having a surgery. In case, NHS funding is unavailable for the lens type required by the patient, they can simply pay privately for the cataract surgery.

Post Surgery

This is a simple surgery. Hence, most people can go home only a few hours after the accompishment of surgery. The patient will require someone to assist in travelling back home. The surgeon will apply a pad over patient’s eye. It is common to feel a little discomfort for around 24 hours after surgery.

In case of poor vision with the other eye, it is common to feel discomfort and problem with vision for a few days initially after the operation. Some patients may also feel slight discomfort in and around eye area post surgery which improves within a few days.

Side Effects

Complications post surgery (some days and weekes after) are very rare. However, it is crucial to get in touch with a specialist or hospital immediately in case there of pain or loss of vision.

Surgical Instruments Uses and Precautions

These days, spread of harmful germs and infections are quite common in hospitals and medical facilities. Hence, certain guidelines have been outlined for all hospitals and medical centres to ensure control over infection and prevent serious injuries, infections, and illnesses during surgical procedures.

Listed below are some precautionary guidelines for usage of surgical instruments to avoid serious complications:

Sharp Surgical Instruments and Needles – Use and Care

All health care professionals should adhere to the Safety and Prevention Act while handling surgical instruments. It is also crucial to keep a proper record of occupational injuries and illness. The record or log should at least comprise of the following listed below:

• The brand of device involved in incident
• The type of device involved in the incident
• The exact location of the incident
• Proper description of the incident

Instructions on Use of Surgical Instruments:

• Strictly avoid recapping used needles.
• Do not manipulate used needles using both hands or any other method involving directing the needle point towards any part of the body.
• Once used, all disposable syringes, scalpel blades, needles, and other sharp items must be placed for disposal in special puncture-resistant containers. The containers must be placed as close to the use area as possible and practical.
• Special care should be taken while undertaking procedures involving multiple injections with a single needle. Here, it is important that the unsheathed needle is placed at a location where the possibility of contamination is nil. The site should also avoid situations contributing to unintentional needle sticks amid injections.

Precautions while Using Surgical Supplies during Operation

Proper Handling

One of the most crucial aspects to take into consideration with surgical instrumentation is proper handling. Wearing special medicated gloves and getting equipped with complete knowledge about each instrument is a must.

Cleaning of Instruments

Prior to sterilization or any kind of high-level disinfection, the surgical instruments should be cleaned systematically. All of the instruments should be scrubbed thoroughly with soap and water. Special detergent solution can also be used. Many hospitals and medical facilities use mechanical devise ultrasonic cleaners which are acceptable. Here, it is recommended to use covered ultrasonic cleaners to ensure enhanced cleaning efficiency. This also reduces the handling of sharp instruments and the dangers involved.

Gloves for Handling

It is important to wear utility gloves while handling contaminated instruments. This decreases the chances of infections.

Sterilization

All of the surgical supplies should be sterilized and cleaned properly before surgical use. Most of the surgical instruments in conjunction with other products are employed to maintain sterility all through the surgery. Hence, special care should be taken to clean the instruments properly and dipping these regularly in sterilized water. It helps prevent blood coagulation on the surface of surgical instruments.

Proper Disposal

Single-use disposable instruments are meant to be used only once. Hence, after using these for a single patient, proper discarding techniques should be followed. These should not be cleaned, sterilized, or disinfected for second usage under any circumstances.

Best Way to Clean your Surgical Instruments

In order to make sure that patients don’t get transmitted with serious infections or diseases, it is vital that medical practitioners and all hospital technicians adopt proper procedures and guidelines for effectively cleaning and sterilizing surgical instruments.

There are a number of methods that can be adopted by technicians in hospitals to guarantee well kept and thoroughly clean surgical instruments. Listed below are the best ways to clean surgical instruments:

Proper Rinsing

The first step is to rinse all of the instruments immediately after surgery under warm running water. Use of hot water must be strictly avoided. Rinsing should be done properly to remove all traces of blood, tissue, and body fluids.

Cleaning

This should be done on an immediate basis via submerging in a solution of water and neutral PH (7) with appropriate detergent. The cleaning should be done in proper series including the following steps:

Ultrasonic Cleaning

This should be followed for all micro and delicate instruments. The instruments should be processed properly in a cleaner for the complete recommended cycle time which is around 5-10 minutes. Placing of instruments in open position in ultrasonic is crucial. Take special care that sharp blades do not touch other instruments. The solution must be changed frequently.

Automatic Washer Sterilizers

Here, it is important to follow recommendations and instructions given by the manufacturers. The instruments should be lubricated post last rinse cycle and prior to the sterilization cycle.

Manual Cleaning

Although ultrasonic cleaning is deemed as the best and most effective way to clean surgical instruments, the following steps can be taken for if the machine is not available:

Allow air drying the instruments after manual rinsing. Thereafter, the instruments must be stored in a very clean and dry environment.

Autoclaving

In the event where the instruments should be reused or autoclaved, these must be properly lubricated with instrument milk. Strictly avoid using WD-40, oil or other industrial lubricants for the purpose. The instruments must be either put in sets or individually for autoclaving as per the requirement.

Use of Detergents

It is important to use only neutral PH (7) detergents for cleaning surgical instruments as improper rinsing with low PH detergents can lead to breakdown of stainless protective surface. It also promotes black staining.

Brush

Careful brushing of delicate instruments is vital combined with separate handling of general instruments.

Visuals

Make double sure all instrument surfaces are visibly clean. These should also be completely free of stains and tissue. Post scrubbing, it is crucial to rinse instruments thoroughly under running water. While rinsing, technicians must properly open and close Hemostats, Scissors, Needle Holders and all of the other hinged instruments. This will ensure proper rinsing of hinge areas including the exteriors of the instruments. Thereafter, it is time to run dry cycle for the period as recommended by the manufacturer.

Cold Sterilization

The special technique of sterilization involves a 10 hour immersion of surgical instruments in recommended solution.
