CPT ophthalmic sutures are made from raw materials of high biocompatibility, especially for suturing cornea and sclera as they must not elicit acute or chronic inflammation. Suture materials employed in eye surgery are delicate, uniform, homogenous for less tissue distortion and yet have optimum tensile strength. Below are recommended suture material for each tissue:

Ophthalmic Absorbable sutures:

  • CARESORB® – Polyglactin 910 (PGA-PLA) or CARESYN® – Polyglycolic Acid (PGA): muscles, sclera, conjunctiva

Ophthalmic Non-absorbable sutures:

  • CARELON® – Nylon or TRUSTILENE® – Polypropylene: fixation of eyeball, skin/plastic, subcutaneous, cornea, sclera, iris
  • CARESILK® – Silk: cornea, fixation of eyeball, skin/plastic
  • PROTIBOND® – Polyester: muscles, plomb fixation in retinal operation
CARESORB-POLYGLACTIN-910-CPT-SUTURES-Chi-khau-mat

CARESORB®
POLYGLACTIN 910

Multifilament, mid-term wound support: 30 days, complete resorption: 56 -70 days.

CARELON®
NYLON – POLYAMIDE

Monofilament, composed of polyamide 6/6.6, intended for use to suture superficial cutaneous skin and in plastic surgery, general soft tissue approximation, and/or ligation, including use in ophthalmic procedures.
TRUSTILENE-POLYPROPYLENE-CPT-SUTURES-chi-khau-mat

TRUSTILENE®
POLYPROPYLENE

Monofilament indicated for use in general soft tissue approximating and/or ligation, including use in cardiovascular, ophthalmic procedures, and neurological procedures.

PROTIBOND®
POLYESTER

CARESILK®
SILK

Multifilament/braided, composed of an organic protein Bombyx Mori, indicated for use in general soft tissue approximating and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures.

Common sutures for eye surgeries

CARELON® – Nylon USP 10-0 is the most commonly used ophthalmic sutures for closing limbal and corneal wounds, however, progressive hydrolysis of Nylon suture in vivo may result in gradual loss of tensile strength over time.

 

TRUSTILENE® – Polypropylene USP 10/0 (Metric 0.2) is a more permanent suture, which is frequently used for suturing iris or transscleral fixation of intraocular lens (IOL).

CARESORB® – Polyglactin 910 sutures (USP size 8-0 to 6-0) are suitable for suturing subcutaneous tissue, muscle reattachment, conjunctiva…

Ophthalmic suturing requires the surgeons to have a great deal of manual dexterity and steadiness as micro-sutures and needles can be a small as 10 micron in diameter.

High quality ophthalmic needle range

Our AISI 302-304 hard fiber stainless steel needles are siliconized and have very sharp UltraGlyde® needle tip, giving precise and excellent penetration through tissues and maintaining their sharpness after multiple passes.

All micro needles have special surface treatment (with XtraCoat® Silicon) and laser drilled holes with advanced technology, these features provide smooth transition between needle and suture material, thus greatly reduce tissue drags and minimize tissue trauma. In addition, thanks its special geometric design (flattened body), the needle can be gripped firmly with the needle holder, offering maximum stability.

Common surgical needles in ophthalmology

Spatula Needles (Lancet – Side Cutting) with Micropoint (Needle length: 6 mm to 8 mm, curvature 3/8, 1/4 or ½ circle) are used in these ophthalmic procedures: cataract, glaucoma, corneal transplant, strabismus, iris repair, retinal detachment etc.

 

Reverse Cutting Needle (Triangular) with advanced micro point are used for oculoplasty and eye fixation.
