Purpose: To investigate the results of transscleral implantation of foldable intraocular lenses(IOLs).
Methods: Twenty five eyes of 21 patients had transscleral fixation of a foldable IOL combined with conventional 3-port pars plana vitrectomy or anterior vitrectomy. Ten eyes had lens luxation, traumatic and idiopathic. Six eyes were aphakic, 3 after extracapular cataract extraction and 2 as a result of complicated phacoemusifiaction. One patient with a mature cataract and pseudoexfoliation had a wide zonular dialysis during phacoemusifiaction. One patient had an opacified hydrophilic acrylic IOL.
Results: The mean age of the patients was 52.9 years (range 17 to 80 years). The mean preoperative best corrected visual acuity (BCVA) was 1.0 (rang counting fingers to 0.6). The mean preoperative refraction was +10.8 diopter (D) (range+10 to+13) and the mean preoperative astigmatism was 1.8 D (range1.0 to 5.5D). Sixteen IOLs were hydrophobic acrylic, 14 of which were 3-piece AcrySof MA60BM (Alcon) and 2 of which were Senser AR40(Allergan). Four IOLs, all VisaAcry(Staar), were hydrophobic acrylic. The mean power of the IOLs was+22.0D (range 19.0 to 26.0D). The mean follow-up was 12 months(range1 to 18 months). The postoperative BCVA) ranged between 0.05 and 1.0, and the mean postoperative astigmatism was 1.1D (rang 0.5 to 4.0) at the last follow-up visit. The difference was statistically significant (P<0.05). Suture exposure and cystoid macular edema were the only complications, each occurring in 2 eyes.
Conclusion: Transscleral implantation of foldable IOLs takes less time and results in fewer complications and better visual outcomes.
