Comparison of the Techniques of Secondary Intraocular Lens Implantation after Penetrating Keratoplasty

Table 2

Corrected distance visual acuity before and after the secondary IOL implantation.

Characteristics	Total n (%) ()	Preoperative CDVA (range)	Postoperative CDVA (range) After one month	Postoperative CDVA (range) After 6 months
Procedure
IOL in-the-bag implantation	6	0.5–0.8	0.5–0.8	0.5–0.8
IOL in-the-sulcus implantation	11	0.4–0.8	0.3–0.7	0.4–0.9
IOL scleral fixation	29	0.1–0.8	0.2–0.6	0.3–0.8

Preoperative uncorrected VA was below 0.1, and postoperative UCVA, if compared with corrected results was equal or lower; no more than 2 lines on Snellen charts were observed. Postoperative CDVA was better than or equal to preoperative CDVA in 83.3%, 72.2%, and 68.9% of cases, respectively; 2 cases of in-the-sulcus IOL lost more than 2 lines, and 3 cases of scleral-fixation IOL lost more than 2 lines at the end-point.
