Double-Needle Yamane Technique Using Flanged Haptics in Ocular Trauma—A Retrospective Survey of Visual Outcomes and Safety

Abstract

To evaluate visual outcomes and safety of the double-needle technique using flanged haptics (Yamane technique) in patients with aphakia caused by ocular trauma at a trauma referral center. Retrospective: Consecutive interventional case series of 30 patients who underwent the Yamane technique due to posttraumatic aphakia. The double-needle technique using flanged haptics was combined with anterior vitrectomy (group A) in 14 patients, and with pars plana vitrectomy (PPV) (group B) due to retinal detachment, nucleus dislocation into the vitreous cavity, or intraocular lens (IOL) displacement in 16 patients. No intraoperative complications were noted. There was significant improvement in the visual acuity in both groups at the second postoperative visit. However, the visual acuity was significantly worse in the group treated with the Yamane technique combined with PPV. Silicone oil tamponade in PPV group was associated with worse visual acuity, whereas post lensectomy status was associated with poor visual function result in the anterior vitrectomy group. There was one case of slight IOL decentration and one retinal detachment during the postoperative follow-up period in the group with PPV. In this case series, the Yamane technique applied in traumatized eyes was found to be an efficacious and safe procedure. Combining the Yamane technique with PPV due to posterior segment ocular trauma was associated with worse functional results in the follow-up at three months. Further studies with longer follow-up evaluations are required to verify long-term complications.

Outcomes of four-point suture fixated and two-point sutureless posterior chamber IOLs combined with pars plana vitrectomy

“…However, the mean final BCVA was better for the CTL group, which is most likely due to lesser prevalence of comorbidities. For secondary IOL AK implantation [ 11 , 22 , 23 ] and flanged IOL fixation [ 24 ], similar visual and refractive outcomes were reported taking into consideration common ocular history of patients which included RD repair, glaucoma, trauma with and without globe rupture, complicated cataract surgery [ 8 , 25 , 26 ]. The likelihood of certain postoperative complications may be linked to specific surgical procedures, and the degree of improvement in visual outcomes may be linked to the patient’s ocular history [ 25 ].…”

Phacoemulsification Combined With Supra-Capsular and Scleral-Fixated Intraocular Lens Implantation in Microspherophakia: A Retrospective Comparative Study

“…The unique morphology and potential complications of MSP challenge the management of the condition. Various surgical approaches have been attempted in sporadic MSP cases, including angle-supported IOL ( 12 ), iris-claw IOL ( 13 ), retropupillary iris-claw IOL ( 14 ), and sutured ( 15 ) or sutureless ( 16 , 17 ) sclera-fixated IOL. However, most of the procedures adapt lensectomy or capsulotomy to remove the capsular bag, and anterior vitrectomy is often requisite.…”

Visual Outcomes of Pupilloplasty in Ocular Trauma and Iatrogenic Damage

“…Other structures of the eye can be also damaged as a result of trauma, for example the cornea, lens, or posterior segment. Thus, additional surgery may be needed, including intraocular lens (IOL) scleral fixation [ 6 ] or pars plana vitrectomy [ 7 ].…”
