Implantation of an Artisan phakic intraocular
lens for the correction of high myopia, high
hyperopia, aphakia

Purpose

• To evaluate the efficacy of Artisan intraocular
  lens (IOL) for the correction of
• high myopia
• high hyperopia
• aphakia instead of angle fixation ACIOL
• iris or scleral fixation PCIOL.

4
Methods

• 96 eyes of 48 patients with
• 76 high myopia,
• 10 hyperopia
• 10 aphakia
  had Artisan lens implantation to
  correct their refractive errors.

5
Methods

• Postoperative examinations were performed on 1 d,
  1 w, 1 m, 3 m and 6 m after surgery.
• UCVA
• BCVA
• manifest refraction
• intraocular pressure
• complications
  were evaluated.

6
Technique

• Clear corneal incision at the steep meridian.
• Anterior chamber forming with viscoelastic
• PI at the incision site.
• IOL insertion in Anterior chamber and clawing to
  iris
• Suturing of limbal incision with nylon 10-0
• Irrigation/Aspiration (viscoelastic material)

Results

• Preoperative UCVA improved from 20/400 to 20/30
  at 3 months after removal suture.
• Postoperative manifest refraction was -1.00
  0.75 D (-3.00 to -0.00 D) at 3 months after
  surgery, and stabled during the follow-up period.
  
• Postoperative BCVA was 20/25.

9
Complications

• No serious complications such as
• angle closure
• open angle Gluacoma
• progressive endothelial cell loss
• Pupilary block
• Reaction the days after the operation.
• Only 3 eyes were observed with hypopiun

10
Note

• One of the patients was a 42 years old woman with
  aphakia.
• Her refraction before surgery was 13.00D.
• BCVA 10/10.
• After surgery and artisan IOL insertion with
  power of 8.00D her refraction was 23.00D.
• Reoperation was done and artisan IOL was removed.
• We noticed that the power of the IOL was
  negative (about -8.00D).
• The IOL was labeled wrong in the factory.

11
Conclusion

• Currently, implantation of an Artisan iris-claw
  IOL is safe and effective for
• high myopia
• high hyperopia
• aphakia
• Because this operation method has not a serious
  complication such as
• Glaucoma
• Endothelial cell lose
• high quality of VA
• It is better to use this method for high numbers
  instead of PRK, LASIK

Conclusion

• Because this operation method has not a serious
  complication such as
• Glaucoma
• Endothelial cell loss
• high quality of VA
• It is better to use this method for high numbers
  instead of PRK, LASIK, LASEK, Epi- LASIK
