| Popis: | To present our experience with post-traumatic lens dislocation management by vitrectomy followed with sutureless artificial lens fixation. The retrospective study involved 15 patients (12 men and 3 women) aged from 36 to 78 (on average, 63 years old), from the Vitreoretinal Surgery Teaching Hospital, operated in the years 2013–2015. All cases concerned ocular traumas with dislocation of the natural or artificial lens to the anterior chamber, vitreous body chamber, or post-traumatic aphakia. After vitrectomy, patients had the implant fixated with a technique devised by Scharioth—sutureless fixation of posterior chamber implants in the groove area, with haptics placed in scleral tunnels parallel to the corneal limbus. Preoperative and postoperative condition of the eye was assessed. The average period of observation was 29 weeks. Average pre-surgery refraction was + 10.75, while post-surgery + 1.25. Average best-corrected visual acuity in Snellen charts before surgery was 0.3 and at the end of the observation period 0.5. The improvement in visual acuity after surgery in relation to visual acuity before surgery was statistically significant (P = 0.005). In the first 2 weeks after surgery, minor hypotonia was observed in three of the patients, while in two—moderate bleeding to the vitreous body and the anterior chamber, which subsided without surgical intervention. A slight decentration of the implant observed in two cases did not affect later refraction or BCVA. Basing on the abovementioned facts, we believe that this surgical approach facilitates the fixation of the dislocated lens and allows a successful treatment of secondary implantation or repositioning of a dislocated intraocular lens. |
