BACKGROUNDCollagen is the most abundantly present connective tissue. In higher animals, primarily as extracellular insoluble fibres and the fibres account for large part of organic mass of skin, tendon, blood vessel, bone teeth, cornea and vitreous humour. Collagen also provides the framework of parenchymal organs and basement membrane. The collagens constitute a family of proteins selected during evolution for the execution of several (mainly structural) functions. During the process of evolution of multicellular organisms, a family of structural proteins was selected by both environmental influences and the functional requirements of the animal organism and developed to acquire varying degrees of rigidity, elasticity and strength. These proteins are known collectively as collagen and the chief examples among its various types are present in the skin, bone, cartilage, smooth muscle and basal lamina. Collagen is the most abundant protein in the human body representing 30% of its dry weight. The collagens are produced by several cell types and are distinguishable by their molecular compositions, morphologic characteristics, distribution, functions and pathologies. More than 20 types of collagen have been identified and designated with Roman numerals; the most important of these are listed in Table 5-3. They are classified into the following four categories according to their structure and general functions.

“…shaving of the vitreous base can release vitreoretinal traction to avoid postoperative retinal tear or detachment. [12,31] Although our patients had coexistent ocular conditions, the postoperative BCVA was significantly different from the preoperative BCVA (P = 0.011). However, the BCVA did not improve in 4 cases during the follow-up period.…”

Background: To report a modified surgical technique for intrascleral intraocular lens (IOL) fixation with fewer anterior segment manipulations in eyes lacking sufficient capsular support. Methods: Eyes from 14 patients who underwent 27-gauge needle-guided intrascleral IOL fixation with built-in 8-0 absorbable sutures were studied. The 8-0 absorbable sutures were inserted into 27-gauge round needles and used to create sclerotomies at the 4 o’clock and 10 o’clock positions under the scleral flap. The sutures were used to tie knots at the end of each haptic and guide haptic externalization through the sclerotomy. After externalization, a sufficient flange was created at the end of each haptic and fixed under the scleral flaps. The best corrected visual acuity (BCVA), corneal endothelial cell density (ECD), IOL tilt and decentration, previous surgery history, and complications were determined. Results: Fourteen cases were analyzed. The majority of eyes exhibited an improvement in the BCVA after surgery. When comparing the last follow-up to preoperative visual acuity, the mean change in BCVA was + 26.32 letters (p=0.011). Postoperative complications included postoperative hypotony in 3 eyes, ocular hypertension in 2 eyes. No cases of postoperative cystoid macular edema (CME), vitreous hemorrhage (VH), IOL dislocation, or endophthalmitis were observed. Conclusions: The 27-gauge needle-guided intrascleral IOL fixation technique with built-in 8-0 absorbable sutures is easy to perform with fewer anterior chamber manipulations and achieves both anatomical and optical stability.
