  • Gonioscopy after implantation of the semiflexible McGhan/3 M, style 70, Anterior Chamber Lens. A prospective study.
    Acta Ophthalmologica, 2009
    Co-Authors: Kristian Næser, Jørgen Nørrelykke Nissen, Tom Eggert Hansen
    Abstract:

    Gonioscopy was performed in 64 patients 3-8 (mean 4) months after intracapsular cataract extraction with implantation of the semiflexible McGhan/3 M, style 70, Anterior Chamber Lens. Iris tucking was present in 19 (30%) eyes. Iris-haptic adhesions (strands of iris-like tissue encircling the Lens feet) were present in 24 (38%) eyes. Absence of iris tucking was statistically significantly (P less than or equal to 0.05) related to surgical expertise, while the occurrence of iris-haptic adhesions was independent of surgical experience. Pupillar deformation, usually an elongation in the axis of the implant, was present in 50%. The absence or presence of an abnormal gonioscopy could not with certainty be deduced from the form of the pupil. The majority of gonioscopically visible pathological changes in the Chamber angle were located posterior to the trabecular meshwork.

  • Complications and visual outcome 4 months after implantation of the semiflexible McGhan/3M, style 70, Anterior Chamber Lens. A prospective study.
    Acta Ophthalmologica, 2009
    Co-Authors: Jørgen Nørrelykke Nissen, Kristian Næser, Tom Eggert Hansen
    Abstract:

    A report is given of visual outcome and intraocular complications in 64 patients 3-8 months after implantation of Anterior Chamber Lens. 80% had a final visual acuity of 0.50 or better. Visual acuity below 0.50 could in most cases be related to pathological findings in the eye independent of implant. Pupillary block was found in 4 cases (6%), and at re-examination they all had gonioscopic changes. The mechanism of pupillary-block-glaucoma with IOL Lens implantation and measures to meet this is discussed. Gross tucking was found to pre-dispose to chronic inflammation. Cystoid macular oedema (3%) and retinal detachment (2%) was found without obvious relationship to gonioscopic changes.

  • Intraocular pressure 4 months after implantation of the semiflexible McGhan/3M, style 70, Anterior Chamber Lens. A prospective study.
    Acta Ophthalmologica, 2009
    Co-Authors: Tom Eggert Hansen, Kristian Næser, Jørgen Nørrelykke Nissen
    Abstract:

    . Sixty-four patients were consecutively operated for senile cataract with implantation of the semiflexible McGhan/3M, style 70, Anterior Chamber Lens. Intraocular pressure (IOP) was measured one day prior to the operation, 6 days and 3–8 months (mean 4 months) after the operation, and gonioscopy was performed one day prior to and 4 months after the operation. A significant fall in IOP was found in the operated eye 6 days after surgery. No significant change in IOP was found 4 months after surgery, neither in the operated eye nor in the non-operated fellow eye. Iris tucking seemed to have no influence on the postoperative tension, while a significant rise in IOP was found in 13 eyes with adhesions between the iris and Lens haptics as the only abnormal gonioscopic finding.

  • Primary or secondary Anterior Chamber Lens implantation after extracapsular cataract surgery and vitreous loss
    Eye, 1991
    Co-Authors: P G Hykin, I D Gardner, M C Corbett, H Cheng
    Abstract:

    Whilst an Anterior Chamber Lens implant (AC IOL) can be implanted during extracapsular cataract extraction with vitreous loss managed by Anterior vitrectomy, Lens implantation as a secondary procedure may avoid complications. We reviewed 47 consecutive cases of vitreous loss, 37 managed with primary and 10 with secondary AC IOLs. There was no significant difference in the level of final visual acuity but, as expected, it was reached earlier in the primary group (p

We reviewed 47 consecutive cases of vitreous loss, 37 managed with primary and 10 with secondary AC IOLs. There was no significant difference in the level of final visual acuity but, as expected, it was reached earlier in the primary group (p<0.001). In the secondary group post-operative astigmatism was less marked (p<0.05) and the AC IOL haptic feet were correctly sited in the angle more frequently (p<0.05). Primary implant patients experienced more recurrent attacks of Anterior uveitis (p<0.01) although the incidence of cystoid macular oedema and retinal detachment did not differ significantly. The results suggest that correct AC IOL positioning is more likely with a secondary procedure and that post-operative complications are fewer.

  • Anterior Chamber Lens implantation in vitrectomised eyes
    Eye, 2018
    Co-Authors: Guy S. Negretti, M Lai, Petros Petrou, R Walker, David G. Charteris
    Abstract:

    PurposeTo investigate long-term visual acuity (VA) outcomes and complication rates in vitrectomised eyes undergoing Anterior Chamber intraocular Lens (ACIOL) insertion.Patients and methodsA single-centre, retrospective case series including all patients who had undergone ACIOL placement at the time of vitrectomy surgery or having had previous vitrectomy, between January 2007 and January 2013. Patients were identified using an electronic database and paper casefile notes were analysed for all patients. Patients were excluded if they had <3 months follow-up.ResultsTwo hundred and seventy-one patients were included in the analysis. Mean follow-up was 27 months. One hundred and forty-eight patients were vitrectomised before ACIOL placement. One hundred and twenty-three patients underwent vitrectomy at the time of ACIOL placement. Mean best-corrected visual acuity (BCVA) before ACIOL placement was 1.27 LogMar (SD 0.95). Mean BCVA at final follow-up was 0.51 LogMar (SD 0.66) (paired-sample T-test P<0.001). Forty (15%) patients developed postoperative cystoid macular oedema (CMO). Eighty-seven (32%) patients had an intraocular pressure (IOP) rise acutely post ACIOL insertion. Fifteen (6%) patients developed corneal decompensation. Five subsequently required corneal grafting. Sixteen patients had ACIOL displacement or instability requiring further surgery.ConclusionsACIOL insertion after vitrectomy is effective. Ninety-two per cent of patients maintained or gained VA, comparable to previous studies of ACIOL insertion post complicated cataract surgery. Raised IOP was the most frequent complication: 61 patients were on topical therapy at most recent follow-up. CMO tended to be acute. Corneal decompensation was infrequent.
