Vetnuus | February 2025 39 The suture choice I recommend is to consider an absorbable suture that has good tensile strength and will last long enough until the wounds are healed. The safest product that will achieve this is Vicryl (polyglactic acid). It is a braided multifilament material, and it is relatively non-reactive. The main reason for its use with ocular tissues is the safety aspect! A soft multifilament suture is far less likely to cause corneal injuries post-operatively compared to stiff monofilament material such as PDS (Pictures 4 & 5). The volume of the suture increases logarithmically with increasing diameter, and this will increase tissue reaction, knot size and irritation. Therefore, I recommend a thickness of 6-0 for general use or 7-0 for experienced surgeons with access to fine ocular surgical instruments. v Regulars I Ophthalmology Column Please feel free to contact me directly at the Johannesburg Animal Eye Hospital if you need any guidance or advice on your ophthalmology cases. https://forms.gle/rZqjwS3NXNQpSZWt6 Pictures 4 & 5: Post-operative corneal damage caused by PDS sutures used for a Morgan pocket reduction
