Secondary IOL: Improved Vision After Cataract Surgery
Patients undergoing Secondary IOL implantation see notable improvement in visual acuity as various surgical techniques prove effective. A recent study presented at Kiawah Eye revealed that all techniques, including Yamane, led to better vision over time. The Yamane technique showed the most prominent improvement, while younger patients and time passed as surgery also correlated with enhanced outcomes. The research, involving 93 eyes, explored different fixation techniques, including sulcus placement, anterior chamber implantation, and iris claw implantation.

Secondary IOL Implantation Improves Visual Acuity
Updated May 30, 2025
KIAWAH ISLAND, S.C.— Visual acuity improved over time following secondary IOL implantation using various techniques, according to research presented at Kiawah Eye.
Dr. David Baxley presented a retrospective study of patients who underwent secondary IOL implantation. Indications included aphakia, lens dislocation, IOL exchange and complications after trauma.
the primary goal was to assess best corrected visual acuity at different times after surgery, Baxley said.
The study involved 93 eyes of 93 patients, with an average age of 67.8 years.Fixation techniques included Yamane (38%), sulcus placement (27%), anterior chamber IOL implantation (17%), iris claw implantation (6%), four-point scleral (5%), two-point scleral (4%) and hybrid (2%). Follow-up visits occurred at one day, one week, one month, three months, six months and one year.
Baxley reported that all surgical techniques led to meaningful improvements in visual acuity over time. The Yamane technique showed the most prominent betterment (P = .02), increasing visual acuity from 0.5 logMAR at one month to 0.15 logMAR at one year.
“You really can’t go wrong with any of these,” Baxley said, emphasizing that comfort and expertise with a technique often lead to good results.
Younger patient age (P = .03) and time since surgery (P < .01) were also considerably associated with better outcomes. Race, sex and laterality did not significantly affect visual acuity outcomes.
Future research should examine complications linked to secondary IOL implantation, such as hyphema syndrome, vitreous hemorrhage and the need for IOL readjustment, baxley noted.
“We’re seeing a lot of these cases,” he said, highlighting the importance of understanding potential complications.
What’s next
further studies are needed to evaluate long-term outcomes and refine surgical techniques for secondary IOL implantation to optimize visual results and minimize complications.
