简要总结
To minimize multiple manipulations and to decrease the economical burden; here, we describe how to utilize the patient's own dislocated intraocular lens to re-fixate with the sclera.
详细描述
When a scleral fixated intraocular lens (IOL) is displaced; routinely it is extracted and exchanged with another IOL and re-fixated to the sclera or another modality can be used. Both can carry many complications due to multiple manipulations. Nevertheless, suture and/or haptic end exposure is another expected future complication, which can range from foreign body sensation to endophthalmitis.
Here, the investigators utilized the same participant's IOL with minimum manipulations and the haptic ends buried inside scleral pockets to prevent future exposure and complications. The pocket entry is sutured with 8/0 vicryl, which is absorbable, to overcome complications.
