The SWISS IOL Technique (Small-Width Incision Scleral Suture): A Mini-Invasive Technique.

ABSTRACT:

Purpose

To evaluate the outcomes and safety of a minimally invasive technique for sutured IOL scleral fixation in case of compromised capsular and iris support.

Materials and methods

In this retrospective study, we explain our mini-invasive technique and assess the outcomes in terms of visual acuity, pre- or postoperative complications, and IOL position (Sensar AR40e, AMO) in a case series of three patients.

Results

The expected best corrected visual acuity could be achieved after one month. Surgeries were uneventful with a stable eye. No postoperative complications occurred except for one patient who had a conjunctival disinsertion. Neither postoperative hypotony nor raised IOP was found. Additionally, no patient experienced corneal edema at one week control, IOL dislocation, vitreous hemorrhage, or new pupil's irregularity.

Conclusions

In conclusion, each scleral technique has its own advantages and its inherent postoperative complications. To date, there is no evidence of superiority of any single technique. By improving our scleral sutured lens techniques, we could improve peroperative ocular stability, potentially decrease postoperative complication rate, and offer a rapid recovery with a stable visual acuity within a month.

Project description:BackgroundHyperopia is a kind of refractive error in which incoming light is focused behind, instead of on, the retina wall due to insufficient accommodation by the lens. It is likely affected by ethnicity, geography, and a family history of hyperopia or accommodative esotropia and is categorized as low (≤ 2.00D), moderate (2.00-4.00 D), and high (> 4.00D). Beyond hyperopia refractive error, patients may have poor accommodative function or visual perceptual skills.ObjectiveThis study aimed to present the latest approaches to planning trifocal intraocular lens (IOL) and toric trifocal IOL implantation for residual refractive errors in young adults with high astigmatism and hyperopia and increase the patients' best visual outcome and satisfaction using Small Incision Lenticule Extraction (SMILE) after implantation.MethodsEighty eyes of 40 consecutive patients who underwent refractive lensectomy were included in this retrospective study. It included patients aged 20-45 years seeking spectacle independence with pre-operative high spherical hypermetropia of 4D or higher and astigmatism of 3D or higher. Patients' treatment status was categorized as trifocal IOL (n=40) and toric trifocal IOL (n=40).The mean patient follow-up time was six months after IOL implantation. First, we assessed visual acuity and satisfaction for both groups and then examined laser vision correction results of patients who were dissatisfied after IOL implantation (trifocal IOL group) and underwent SMILE surgery to increase satisfaction level.ResultsThere were no statistically significant differences between trifocal IOL and toric trifocal IOL for near (UNVA), intermediate (UIVA), and distance (UDVA) uncorrected visual acuity. Comparisons related to patient satisfaction six months after IOL implantation were statistically significant for using a computer and night driving. In the trifocal IOL group, compared to pre-operative values, sphere and cylinder at six months were significantly improved.ConclusionIn young adults, toric trifocal and trifocal IOL provided sufficient results in visual acuity; however, patients were dissatisfied after implantation. This study reported patient satisfaction levels, including quality of life and life without glasses by using Small Incision Lenticule Extraction (SMILE) surgery.
