Cataract surgery

Cataract training modules

Cataract interface

Lifelike training environment

For training of anterior segment surgery, the Eyesi Surgical platform can be equipped with a cataract interface consisting of a patient model head and instrument set. During virtual surgery, cataract instruments such as forceps, visco cannula, cystotome, and phaco probe are available. An OR machine interface and a two-axis phaco foot pedal allow controlling fluidics.

Training modules

Software packages

The Eyesi cataract training modules offer an immersive environment for training of surgical steps, including capsulorhexis, hydrodissection, phaco divide & conquer and phaco chop, irrigation & aspiration, and IOL insertion. Advanced training modules also present complicated situations such as floppy iris syndrome, weakened zonules, or posterior capsule rupture requiring anterior vitrectomy.

Embedded curriculum

Step-by-step to expert performance

The Eyesi Surgical cataract courseware is organized into four tiers of ascending difficulty. Abstract simulation tasks aim to train basic microsurgical skills, such as instrument navigation in the anterior chamber, tremor control, fine motor dexterity, and proper microscope use. In the next tier, isolated steps of cataract surgery are trained, such as capsulorhexis, lens segmentation, lens removal, and intraocular lens insertion. Then, the acquired cataract skills are refined through more challenging scenarios: trainees practice advanced surgery techniques, such as vertical chopping or insertion of a toric IOL, and perform multistep cataract procedures, for example, the complete phaco divide and conquer technique. Finally, difficult cataract cases and complication are presented.

Advanced cases

Being prepared for complications

In the more advanced Eyesi cataract courses, trainees can practice complications management in a controlled and safe environment. Available training modules feature rescuing an errant rhexis tear, implanting a capsular tension ring, or inserting an iris expansion ring in patients with floppy iris syndrome. In the anterior vitrectomy module, trainees can use two irrigating instruments simultaneously, e.g., the irrigator and the viscoelastic cannula, to practice the skills necessary to maintain the pressure in the anterior chamber and avoid a chamber collapse and loss of visco.

Cataract online course

Comprehensive medical content on VRmNet

The online medical courses on VRmNet complement the practical simulator tasks and provide medical background knowledge on all aspects of cataract surgery. The online courses cover the whole cataract procedure, ranging from patient preparation to white cataracts and complication management.

Cataract challenge course

Benchmark over time

The Cataract Challenge course has been designed to benchmark residents’ training performance over time. The course mimics the conditions of real surgery. Every 60 minutes of training time, trainees must perform a complete cataract procedure in sequential order. They only have one attempt at each cataract step and a limited time window of 15 minutes.
